feat(3p): add haskell-language-server r/1203

Add expression for building haskell-language-server, based on a vendored
version of https://github.com/korayal/hls-nix with hashes updated to
work with our nixpkgs version and ghc 8.8.3. Also add that to CI
builds, so whitby will build it for me (thanks whitby).
