Steps to Reproduce

1. Check the docs for gamehighscore
2. No returned in admonition present

Expected behaviour

It should show Returned in Bot.get_game_high_scores.

I propose refactoring the code of AdmonitionInserter._resolve_arg, since that is why this fails. I am unsure why typing.get_origin is used instead typing.get_args. Moreover, we can let python resolve forward refs, as we've done recently in test_official, which should reduce complexity.

Actual behaviour

Nothing shown.
