Fix statistics wedge not showing correct values in daily challenge

Hey friends! Thought this was a decent issue to look at as my first contribution 😃

Fixes #29094

I did wonder if this should be done in a value changed binding on OsuScreen.Beatmap, but this seems simple & clear enough that this should happen when we do other beatmap setting stuff

Turns out I'm a noob at GitHub's pull request flow - I think I totally could've taken your change directly from that suggestion @bdach 😅

Nah that was not a github suggestion, that was a git patch. If you could commit directly via github there'd be a button (but there's none).
