Difficulty attributes in multiplayer and playlist extra mod select are not correctly shown

Cosmetic

Bug description

• When selecting extra mods in a multiplayer room, the star rating (at the bottom of the mod select screen) are not shown correctly when SR-changing mods are selected.
  • The shown SR seems to be the SR before the last mod is selected/canceled.
  • Other diff attributes are shown correctly.
• When selecting extra mods in a playlist, all diff attributes (including star rating) are shown as 0.
• Mod select in song select (both single & multiplayer) displays correct diff attributes.

edit: I believe the issue is that the updateTrackedBindables() method in BeatmapDifficultyCache.cs is not being called when the first mod is selected...

Doesn't seem to be just for the first mod select. Looks like this is always 1 version late for some reason. So the first mod change doesn't even trigger the callback here, the second change triggers it but the event value corresponds to the first change, then the third change's event value corresponds to the second event, and so on.

@smoogipoo Probably one for you to have a quick look at (unsure if this was always broken or might be a potential regression)

Looks like it'll be fixed by #32669
