Move Away from update-notifier

[loren138]

update-notifier has a transient security risk as it eventually uses an old version of got

Sadly, to update to the newest version, you'd have to move to esm.
See: https://github.com/yeoman/update-notifier/releases/tag/v6.0.0

I'm personally fine using it without any update-notifier at all.

But if one is desired, you could follow in the footsteps of nodemon and switch to simple-update-notifier which has far less dependencies. (See: remy/nodemon#2033)

I'm happy to help with a PR for either change but would like a maintainers approval and direction first.
