haskell: add vscode with extensions

Seems that it does not work as expected.

    # VSCode hde setup
    # https://github.com/haskell/haskell-ide-engine#using-vs-code-with-nix
    ((pkgs.vscode-with-extensions.override{
      vscodeExtensions = with vscode-extensions; [
        bbenoist.Nix
      ] ++ vscode-utils.extensionsFromVscodeMarketplace [
        {
          # justusadam.language-haskell
          name = "language-haskell";
          publisher = "justusadam";
          version = "2.4.0";
          sha256 = "1xgxs0s3w5kf356nslf020svn2hr6dq216ndwjk23v6mqs1xfxgv";
        }
        {
          # alanz.vscode-hie-server
          name = "vscode-hie-server";
          publisher = "alanz";
          version = "0.0.27";
          sha256 = "1mz0h5zd295i73hbji9ivla8hx02i4yhqcv6l4r23w3f07ql3i8h";
        }
      ];
    }).overrideDerivation (old: {
      postFixup = ''
        wrapProgram $out/bin/code --prefix PATH : ${lib.makeBinPath [
          # Install stable HIE for GHC 8.6.4 (multiple ghc versions are allowed)
          (all-hies.selection { selector = p: { inherit (p) ghc864; }; })
        ]}
      '';
    }))

this kinda works, but the hie does not start at the end
