fix: Ignore comments in commit file

[deckstose]

The linted file can contain comments, especially when commit message templates are used, which lead to comments being linted as a message, not the message used by git.

I'm not really happy with what I came up with, I'll take another look tomorrow.

Maybe it's best to remove trim_commit_file, after a round of take_while and filter to strip comments there is not much left to do.
