Subject: [PATCH]  Fix dirty `Cargo.lock` changes appearing after install
 (`base64`) (#18689)

Normal install results in `Cargo.lock` changes constantly popping up for me as I navigate my
branches. This was probably caused by some Depdendabot PR updating the
`Cargo.toml` without `Cargo.lock` or something.

```
poetry install --extras all
```

In another PR, I've also added CI to ensure we don't leave `Cargo.lock`
changes behind to avoid this annoyance in the future ->
