Support for reverting commits

[krlvi]

@krlvi I was planning to take a stab at this. Is this something external contributors can help with? I'll be able to complete it in a week.

I was planning to add a "Revert" button here besides the Undo ( Or maybe it can be inside a meatball menu icon )

Pressing the button should run the equivalent of 'git revert '. Thoughts?

[krlvi]

I imagine this working as an "apply the reverse of commit X into the working directory". Basically the equivalent of
git show <sha> | git apply -R

It could be nice to support doing it for the entire commit or for a specific file, the equivalent of git show <sha> path/to/file | git apply -R

A new API / tauri command would be needed here, this particular one may get quite involved

I'll still like to take a stab at it ( Unless its urgent )
I was looking at git2 documentation and found the apply method that we can use.
Couln't find a method for show. Is it fine if we use diff for now?

I'll start with creating the new API & tauri command, in the meantime we can also start a discussion on how the UI would work?
I was thinking

• each file's FileContextMenu would have an item to allow it to reverse the commit for the file
• A revert button besides Undo to revert the whole commit.

Does this work? @krlvi

I would have liked this feature today; just to capture the why: I'd created a PR, and got review comments on it. As a result, I wanted to undo one of the commits, but didn't want to rewrite the history in the existing PR. I wanted a commit that reverts the original commit, to tell a useful, but honest narrative in the commit history in the PR, and without messing up existing reviewers/comments
