Switch to nixpkgs-23.11, ghc 9.6.3

This brings a bunch of improvements. I got rid of some custom packages, I can
now build exllama without using a non-default cuda version. Oh yeah and I get to
use GHC 9.6.2 now, a huge upgrade from 9.4. Unfortunately I also updated ormolu
and some unrelated formatting changed, but that's life I guess.
