Ugit Versions Save

• Support for undoing all current uncommitted changes (uses git stash, for now, future releases might completely delete stuff) 🎉

• ugit now supports picking custom (previous) commits to undo
• You can now undo git cherry-pick. It's nothing fancy, A git cherry-pick is basically a commit

• Friendship with Bash3 lost, Bash4 is my new best friend.
• Fix minor shellcheck linter issues
• ugit is now available as an ohmyzsh plugin. Read Docs to use ugit with ZSH
• ugit now available for AUR users (btw I use Ubuntu)

Big thanks to @sharan-aithal @TabulateJarl8 @unixorn 🤗 🎉 for this release
