Adds a new command `gh auth setup-git [<hostname>]` that sets up git to use the GitHub CLI as a credential helper. The gist is that it runs these two git commands for each hostname the user is authenticated with. ``` git config --global --replace-all 'credential.https://github.com.helper' '' git config --global --add 'credential.https://github.com.helper' '!gh auth git-credential' ``` If a hostname flag is given, it'll setup GH CLI as a credential helper for only that hostname. If the user is not authenticated with any git hostnames, or the user is not authenticated with the hostname given as a flag, it'll print an error. Co-authored-by: Mislav Marohnić <mislav@github.com>
