Bump the minimum required git version to 2.22 (#4439)

- **PR Description**

For my current work on better cherry-picking/reverting, git versions
older than 2.22 cause considerable headache. Apparently they have issues
with `git cherry-pick --continue` and `git cherry-pick --skip` which I
would prefer not to have to work around.

The last time [we
discussed](https://github.com/jesseduffield/lazygit/issues/2457#issuecomment-1436767849)
the question of bumping the minimum version from 2.20 to 2.22, we
decided not to because 2.22 is 6 months newer. That was two years ago
though, so now it should be fine, I guess.
