update sample config

Lets you override the default power levels for rooms created on this server, per
room creation preset.

Useful if you know that your users need special permissions in rooms
that they create (e.g. to send particular types of state events without
needing an elevated power level).  This takes the same shape as the
power_level_content_override parameter in the /createRoom API, but
is applied before that parameter.

This is something of a workaround in the absence of MSC3779 or MSC3761.

-Synapse 1.60.0 (2022-05-31)
-===========================
-
-This release of Synapse adds a unique index to the `state_group_edges` table, in
-order to prevent accidentally introducing duplicate information (for example,
-because a database backup was restored multiple times). If your Synapse database
-already has duplicate rows in this table, this could fail with an error and
-require manual remediation.
-
-Additionally, the signature of the `check_event_for_spam` module callback has changed.
-The previous signature has been deprecated and remains working for now. Module authors
-should update their modules to use the new signature where possible.
-
-See [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1600)
-for more details.
-
-Bugfixes
---------
-
-- Fix a bug introduced in Synapse 1.60.0rc1 that would break some imports from `synapse.module_api`. ([\#12918](https://github.com/matrix-org/synapse/issues/12918))
-
-
-Synapse 1.60.0rc2 (2022-05-27)
-==============================
-
-Features
---------
-
-- Add an option allowing users to use their password to reauthenticate for privileged actions even though password login is disabled. ([\#12883](https://github.com/matrix-org/synapse/issues/12883))
-
-
-Bugfixes
---------
-
-- Explicitly close `ijson` coroutines once we are done with them, instead of leaving the garbage collector to close them. ([\#12875](https://github.com/matrix-org/synapse/issues/12875))
-
-
-Internal Changes
-----------------
-
-- Improve URL previews by not including the content of media tags in the generated description. ([\#12887](https://github.com/matrix-org/synapse/issues/12887))
-
-
-Synapse 1.60.0rc1 (2022-05-24)
-==============================
-
-Features
---------
-
-- Measure the time taken in spam-checking callbacks and expose those measurements as metrics. ([\#12513](https://github.com/matrix-org/synapse/issues/12513))
-- Add a `default_power_level_content_override` config option to set default room power levels per room preset. ([\#12618](https://github.com/matrix-org/synapse/issues/12618))
-- Add support for [MSC3787: Allowing knocks to restricted rooms](https://github.com/matrix-org/matrix-spec-proposals/pull/3787). ([\#12623](https://github.com/matrix-org/synapse/issues/12623))
-- Send `USER_IP` commands on a different Redis channel, in order to reduce traffic to workers that do not process these commands. ([\#12672](https://github.com/matrix-org/synapse/issues/12672), [\#12809](https://github.com/matrix-org/synapse/issues/12809))
-- Synapse will now reload [cache config](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#caching) when it receives a [SIGHUP](https://en.wikipedia.org/wiki/SIGHUP) signal. ([\#12673](https://github.com/matrix-org/synapse/issues/12673))
-- Add a config options to allow for auto-tuning of caches. ([\#12701](https://github.com/matrix-org/synapse/issues/12701))
-- Update [MSC2716](https://github.com/matrix-org/matrix-spec-proposals/pull/2716) implementation to process marker events from the current state to avoid markers being lost in timeline gaps for federated servers which would cause the imported history to be undiscovered. ([\#12718](https://github.com/matrix-org/synapse/issues/12718))
-- Add a `drop_federated_event` callback to `SpamChecker` to disregard inbound federated events before they take up much processing power, in an emergency. ([\#12744](https://github.com/matrix-org/synapse/issues/12744))
-- Implement [MSC3818: Copy room type on upgrade](https://github.com/matrix-org/matrix-spec-proposals/pull/3818). ([\#12786](https://github.com/matrix-org/synapse/issues/12786), [\#12792](https://github.com/matrix-org/synapse/issues/12792))
-- Update to the `check_event_for_spam` module callback. Deprecate the current callback signature, replace it with a new signature that is both less ambiguous (replacing booleans with explicit allow/block) and more powerful (ability to return explicit error codes). ([\#12808](https://github.com/matrix-org/synapse/issues/12808))

-- Fix a bug introduced in Synapse 1.57.0 where `/messages` would throw a 500 error when querying for a non-existent room. ([\#12683](https://github.com/matrix-org/synapse/issues/12683))

-- Require a body in POST requests to `/rooms/{roomId}/receipt/{receiptType}/{eventId}`, as required by the [Matrix specification](https://spec.matrix.org/v1.2/client-server-api/#post_matrixclientv3roomsroomidreceiptreceipttypeeventid). This breaks compatibility with Element Android 1.2.0 and earlier: users of those clients will be unable to send read receipts. ([\#12709](https://github.com/matrix-org/synapse/issues/12709))
-
-

-----------------
-
-- Improve event caching mechanism to avoid having multiple copies of an event in memory at a time. ([\#10533](https://github.com/matrix-org/synapse/issues/10533))

-- Add `@cancellable` decorator, for use on endpoint methods that can be cancelled when clients disconnect. ([\#12586](https://github.com/matrix-org/synapse/issues/12586), [\#12588](https://github.com/matrix-org/synapse/issues/12588), [\#12630](https://github.com/matrix-org/synapse/issues/12630), [\#12694](https://github.com/matrix-org/synapse/issues/12694), [\#12698](https://github.com/matrix-org/synapse/issues/12698), [\#12699](https://github.com/matrix-org/synapse/issues/12699), [\#12700](https://github.com/matrix-org/synapse/issues/12700), [\#12705](https://github.com/matrix-org/synapse/issues/12705))
-- Enable cancellation of `GET /rooms/$room_id/members`, `GET /rooms/$room_id/state` and `GET /rooms/$room_id/state/$event_type/*` requests. ([\#12708](https://github.com/matrix-org/synapse/issues/12708))

-Synapse 1.59.1 (2022-05-18)
-===========================
-
-This release fixes a long-standing issue which could prevent Synapse's user directory for updating properly.
-
-Bugfixes
-----------------
-

-
-Synapse 1.59.0 (2022-05-17)
-===========================
-
-Synapse 1.59 makes several changes that server administrators should be aware of:
-
-- Device name lookup over federation is now disabled by default. ([\#12616](https://github.com/matrix-org/synapse/issues/12616))
-- The `synapse.app.appservice` and `synapse.app.user_dir` worker application types are now deprecated. ([\#12452](https://github.com/matrix-org/synapse/issues/12452), [\#12654](https://github.com/matrix-org/synapse/issues/12654))

-===========================
-
-This patch release includes a fix to the Debian packages, installing the
