Bojangalic/Add git command functionality into serve command, and keep both commands

[BojanG99]

Related to #54

Git command isn't deleted here since we want to ensure smooth transition on servers. Deleting it now would break current setup.

Code review checklist (for code reviewer to complete)

• Pull request represents a single change (i.e. not fixing disparate/unrelated things in a single PR)
• Title summarizes what is changing
• Commit messages are meaningful (see this for details)
• Tests have been included and/or updated, as appropriate
• Docstrings have been included and/or updated, as appropriate
• Standalone docs have been updated accordingly

Automated tests, benchmarks and linters

You can run the tests, lints and benchmarks that are run on CI locally with:

just ci

Left a question. Would be awesome if we were able to simplify. Let me know what you think. I believe we can close out #64 in favor of this pr?

Small comment. I believe we can resolve in a separate pr (where we add docs)
