Add recaptcha_{private,public}_key_path config option (#17984)

Another config option on my quest to a `*_path` variant for every
secret. Adds the config options `recaptcha_private_key_path` and
`recaptcha_public_key_path`. Tests and docs are included.

A public key is of course no secret, but it is closely related to the
private key, so it’s still useful to have a `*_path` variant for it.
