feat: support bare repos

[Fabrice-Bernes]

Feature Description
Before checking for a .git directory, use the value of $GIT_DIR

Use Case
This is useful for people who like to use separate version control on files that exist in the same place. We move/rename .git to a separate place, and then export GIT_DIR=/path/to/gitdir, or run git commands with the --git-dir=/path/to/gitdir flag.

Proposed Implementation
None.

Alternatives
I guess a flag would work too, or both.

Ps: gitlogue is cool. Thank you for making it.

Thank you for the feature request and for using gitlogue! 🙏

I understand the use case - supporting $GIT_DIR would be helpful for users managing multiple Git repositories on the same files.

However, this is a somewhat niche use case, so I'll keep this issue open but the priority for implementation is currently low. I may revisit this in the future, but no timeline at the moment.

Thanks again for the suggestion!
