lib.mkRenamedOptionModule: does not handle mkForce priority

[nbraud]

Describe the bug

Evaluating a module containing renamed options (using lib.mkRenamedOptionModule) set by their old name with mkForce priority, results in the following error:

error: A definition for option `bar.enable' is not of type `boolean'. Definition values:
       - In `<unknown-file>':
           {
             _type = "override";
             content = true;
             priority = 50;
           }

Steps To Reproduce

Evaluate the following:

with (import <nixpkgs> {}).lib;
evalModules {
  modules = [{
    imports = [
      (mkRenamedOptionModule [ "foo" ] [ "bar" ])
    ];

    options.bar.enable = mkEnableOption "bar";

    config.foo.enable = mkForce true;
  }];
}

Try again without mkForce

Expected behavior

Successful evaluation, with or without mkForce.
