Deprecate Mackup in my setup

Since macOS 14 (Sonoma), Mackup has been broken 😞

See here:
- lra/mackup#1924
- https://www.reddit.com/r/macapps/comments/1f1j41a/avoid_mackup_if_you_are_runing_sonoma_or_later/

There are some workarounds but I am taking this opportunity to just simplify my setup a bit

Most of my settings are not that precious that I rely on Mackup to perfectly replicate between machines; I can just do some manual configuration and get most of the way there

I'm removing references to Mackup and its configuration from this repo in this commit
