Fix formatter registration pattern

The formatter should be registered for all files that end in `.yaml` or
`.yml`. The old pattern didn't do this properly. This new pattern should
work from my testing.

This should mean we don't need to add new entries for each language
that's based on YAML (eg. dockercompose, ansible, etc.) in the future.
