Check Atom Git API and see if parts can use it instead

[keevan]

Check and see if we can use the api and get git operations for free

See https://flight-manual.atom.io/api/v1.57.0/GitRepository/#instance-getCachedPathStatus

If my theory is correct, this should mean:

• well/better supported api
• no custom git commands (if everything needed is covered)
• which if the above is true means less code which means less issues!
• also some results might use a form of cache, which would mean it should be slightly faster anyways.

That said, still only might be helpful but might not replace the whole thing ~
