core: Add more .github/settings.yaml

IMPORTANT

- Requires Github Settings app to be installed.
- Use of the Github Settings app inherently escalates anyone with push
  permissions to the admin role, since they can push config settings to
  the master branch, which will be synced to the Github repository.
