This prevents Icepeak from being built using the wrong versions after a `cabal update`. We could disable Hackage completely but that would break non-Nix builds.

Might need a nix develop - it failed on CI because it cannot find cabal

You're right, I forgot there's no devenv there. Should be fixed now.

This prevents the plain Cabal and the Nix builds from using different versions. This is especially important when using Nix, as Cabal may start using more up to date versions of the package from Hackage if the user has run
cabal updatebefore and a local package database exists. Cabal can also be forced to use only the global package registry in which case this problem also doesn't exist, but that requires either breaking non-Nix builds or wrapping thecabalcommand.I also added the freeze files to the Nix builds so we'll get alerted if nixpkgs gets updated without also updating the freeze file.
