Ref:

- 33f3ccd6ae/CHANGELOG.md (L134-L136)
- 7165d3fa58/appservice/registration.go (L30)

Intentionally not removing the old configuration setting yet, as some bridges may/do not support
the new setting name. It's likely just bridgev2 mautrix bridges that have been updated and support both right now.
