Update haskell.nix and HLS

[Anviking]

• Bump haskell.nix
• Update Haskell Language Server to 1.5.0.0 in build-tools.nix
• Bump index-state in cabal.project.

Comments

• Build got stuck locally; trying in CI

• Seems to build fine, but HLS doesn't seem updated (when I tried changing manually, it was reverted by the automatic nix regeneration)

• Hydra jobset

This is what I got when trying to run nix-shell locally:

trace: ERROR: cabal configure failed with:

On Hydra, the same error appears as:

Let's try again with latest Hackage and index-state.

It's not all finished building yet, but with the index-state change, hls 1.5 seems to work at least, when building locally.

haskell-language-server version: 1.5.0.0 (GHC: 8.10.7) (PATH: /nix/store/pgzd2bzrlpa4fd473x974say97gwkzz3-haskell-language-server-exe-haskell-language-server-1.5.0.0/bin/haskell-language-server)
