Add git info options

[AngelVenchev]

It'd be great to add options to include git info like current branch or maybe tag or commit hash prefix if none of the above are existant and also a good fallback to empty if you're not in a git repo.

Thank you for your request, and that would be good 👍 To display and format git info on zsh prompt, it's required to write zstyle ':vsc_info:git:*' ... not only PROMPT env var. So it might takes a time to implement it, but I (or someone) will try it!
