Skip post-checkout hook when discarding changes

[stefanhaller]

• PR Description

Some people have post-checkout hooks that take a lot of time, which makes discarding changes slow. You can argue that a post-checkout hook should only run when you switch branches, so it doesnt't have to run when checking out single files or directories. You can also argue that lazygit might have implemented discarding changes by taking the current patch and applying it in reverse, which wouldn't have run a post-checkout hook either.

So disable them for all cases where we use git checkout with a path; this includes checking out a file from the commit files view.

Fixes #4272.
