Subject: [PATCH] Fix the pre-commit `files` regex pattern

The bare `.` matches any single character, which allowed for
a file named e.g. `CITATION-cff` to match in an external repo,
but then cffconvert would throw an error that `CITATION.cff`
could not be found.

This is fixed by escaping the `.` in the `files` regex pattern
so that only a file named exactly `CITATION.cff` will match.
