Fixes https://github.com/NixOS/nixpkgs/issues/138374 The build failure in the above issue is due to `pkgs.dhallPackages.dhall-packages` transitively depending on an older Prelude version (12.0.0) that is incompatible with newer Dhall versions. I first attempted to upgrade `pkgs.dhallPackages.dhall-packages`, but that failed due to a bad hash on an internal import, so I'm removing the build instead.
