Can't create shell with cabal-fmt and GHC 9.10

[m4dc4p]

Describe the bug

When trying to create a shell with GHC 9.10.1 and cabal-fmt, the build fails with the following error:

error: The Haskell package set does not contain the package: os-string (build dependency).

This is using the latest haskell.nix.

Steps To Reproduce

This isn't a complete expression but hopefully enough to repro:

{ system ? builtins.currentSystem, compiler-nix-name ? "ghc910" }:
let 
  sources = import ./nix/sources.nix;
  haskell-nix = import sources."haskell.nix" {  };
  
  pkgs = import sources.nixpkgs (haskell-nix.nixpkgsArgs // { inherit system; });

  project = pkgs.haskell-nix.project' {
    inherit compiler-nix-name;
    src = ./.;

    shell = {
      tools = {
        cabal-fmt = {
          version = "latest";
          configureArgs = "--allow-newer=base";
        };
      };
    };
  };
    
in
  { 
    shell = project.shell;
  }

Running nix-shell -A shell will show the problem.
