Cannot install extraCompatPackages as of latest update.

I just pulled down an update this morning, and I was stopped by this error:

error:

       error: The option `programs.steam.extraCompatPackages' in `/nix/store/scbcfz9nm6im7sx2jwkllj4h8fgb5vcg-source/nixos/modules/programs/steam.nix' is already declared in `/nix/store/2h4q1hiszh3gbkpk53ldj4f7kp2n5cjy-source/flake.nix#nixosModules.steamCompat'.

I am not defining the extraCompatPackages anywhere but in that NixOS module, so I think something went wrong here. Needless to say, I should be able to set that to install things like Proton-GE, correct?

Looks like nixpkgs has received an extraCompatPackages option in the steam module. You may remove the nixos module provided by nix-gaming

See NixOS/nixpkgs#293564
