Unable to build for GHC 8.10.5 using Nix flake

[cydparser]

Your environment

NixOS

Steps to reproduce

nix build .#haskell-language-server-8105

Actual behaviour

error: attribute 'ghc8105' missing

       at /nix/store/k5xl2qzja8h08bxpralpcm7c452jkvab-source/flake.nix:125:41:

          124|           # Haskell packages extended with our packages
          125|           hlsHpkgs = compiler: extended haskell.packages.${compiler};

It looks like nixpkgs has never provided GHC 8.10.5.

There was a pull request for it in nixpkgs, but it wasn't merged because of bugs: NixOS/nixpkgs#125987
