Replace git checkout with git switch and add git restore support

Topic

I've just had this idea, is it recommended within lazygit to replace internal use of git checkout in lazygit with git switch for branch operations, and add git restore support for file-level operations

Your thoughts

This separation aligns with modern Git best practices (added in Git 2.23). Also internally, lazygit could encapsulate fallback logic to detect whether the user’s Git version supports these commands and default back to checkout/reset when necessary.

I have been reluctant to make this change so far, because switch and restore have been marked as experimental until very recently. They only became non-experimental in the current 2.51 version, and I wouldn't feel good about using them in older versions.

Maintaining two different code paths based on git version doesn't seem worth it either, for a change that has no real benefit. As long as checkout is not officially marked as deprecated, I see no reason why we shouldn't continue to use it.

Okay that makes sense. I was just wondering haha
