Upgrade nixpkgs, ghc923

I ended up deleting miso, and consequently all files under Hero/ and Miso/,
because I couldn't get miso to build with GHC 9.2.

Other things:

- Niv has been wrapped by Biz/Bild/Deps.hs, so I can extend it to my liking.
- Apply-refact is gone because I couldn't get it to build.
- Disabled python stuff.
