[PATCH] repo-info: add paths.git_dir field

[jayesh0104 <jayeshdaga99@gmail.com>]

Expose the repository's Git directory path through `git repo info`.

This value is currently available via:

    git rev-parse --git-dir

Adding it to `git repo info` allows scripts to retrieve it
through a structured interface.
