Describe the bug

It's no longer possible to nix build outputs other than out:

{
  outputs = { self, nixpkgs }:
    let pkgs = import nixpkgs { system = "x86_64-linux"; };
    in {
      packages.x86_64-linux = {
        test = builtins.derivation {
          system = "x86_64-linux";
          name = "test-0";
          outputs = [ "main" "alt" ];
          builder = "${pkgs.busybox}/bin/ash";
          args = [ "-c" "echo main > $main; echo alt > $alt" ];
        };
      };
    };
}

Steps To Reproduce

$ nix build '.#test'  # broken
error: derivation '/nix/store/nz97m53ivjay0vk6spcr2pdzw3xg68if-test-0.drv' does not have wanted outputs 'out'
$ nix build '.#test^main'  # works

Expected behavior

As with Nix 2.12:

$ nix build '.#test'  # works
$ nix build '.#test^main'  # works

nix-env --version output

nix-env (Nix) 2.15.1

Additional context

Seems to be a regression in between 2.12 and 2.13.
