maintainers/scripts/haskell/regenerate-hackage-packages.sh: init

Introduces a script that can be used to update the Nix expressions for

the Haskell package set. In service of that, also

- introduces cabal2nix-latest, which pins the hackage2nix version used

- changes all-cabal-hashes to use fetchFromGitHub

- adds update-hackage.sh & update-cabal2nix-latest.sh & update-stackage.sh maintainer scripts
