Nixpkgs: Haskell packages: attribute "webkitgtk24x" missing

[langston-barrett]

Issue description

I was running nox-review, and it noticed that the package haskellPackages.leksah wouldn't build. I believe this is because it depends on webkitgtk3, which also won't build, with the same message:

$nix-build -A haskellPackages.leksah .
error: attribute ‘webkitgtk24x’ missing, at /home/siddharthist/code/nixpkgs/pkgs/development/haskell-modules/hackage-packages.nix:202442:10
(use ‘--show-trace’ to show detailed location information)

$ nix-build -A haskellPackages.webkitgtk3                   
error: attribute ‘webkitgtk24x’ missing, at /home/siddharthist/code/nixpkgs/pkgs/development/haskell-modules/hackage-packages.nix:202442:10
(use ‘--show-trace’ to show detailed location information)

@volth Might this have something to do with #26125?

This should get fixed on next haskell-updates, it is already merged into upstream cabal2nix: https://github.com/NixOS/cabal2nix/pull/283

Is there any ETA for haskell-updates? I see that until two weeks ago, the index was being updated every [two to five days](https://github.com/volth/nixpkgs/commits/ab8af93b2693cbc97ff1836f2b1518c0e7f58b57/pkgs/development/haskell-modules/hackage-packages.nix].

We haven't merged haskell-updates recently because we've using that branch to run test builds for https://github.com/NixOS/nixpkgs/pull/27196. Anyhow, I'll generate a quick update and merge it ASAP.
