Allow multiple configurations in programs.chromium

[juangiordana]

Description

Is it feasible for programs.chromium to be a list instead of a set so multiple browser variants can be configured at the same time?

  programs.chromium = [
    {
      enable = true;
      package = pkgs.brave;
      # commandLineArgs = [ ... ];
      # extensions = [ ... ];
    }

    {
      enable = true;
      package = pkgs.chromium;
      # commandLineArgs = [ ... ];
      # extensions = [ ... ];
    }
    # ...
  ];
