Skin anchor menu checkmarks don't update when right-clicking

[Joehuu]

Type

Cosmetic

Bug description

Noticed in #31779 (when the checkmarks didn't hide when increasing fade out time).

Right-clicking the menus also demonstrates this broken behavior better so putting it as the headline.

Should be trivial as this:

osu/osu.Game/Screens/Edit/WaveformOpacityMenuItem.cs

Lines 31 to 35 in 20c4bad

	waveformOpacity.BindValueChanged(opacity =>
	{
	foreach (var kvp in menuItemLookup)
	kvp.Value.State.Value = kvp.Key == opacity.NewValue ? TernaryState.True : TernaryState.False;
	}, true);

but the closest item logic that connects the anchor/origin menus makes it a little more complicated.
