Describe the feature or problem you’d like to solve

When I use gh repo create and specify "Push an existing local repository to Github" on my bare repository, it says "current directory is not a git repository. Run git init to initialize it". To resolve this, I go to the web interface and manually create a new repo. I'd like to request for gh repo create to recognize bare repositories as repositories.

Proposed solution

#6880 was a merged PR that migrated to git rev-parse's --git-dir flag to correctly recognize bare and non-bare repos for another part of the github cli for a similar issue. Although this is what the gh repo create command also does, it only checks if the result is .git, instead of also checking if it's also . in the case of a bare repo. We can check for a . case.

Additional context

This will make the CLI's functionality more streamlined and consistent with user expectations
