nuke holding_disposable_cup_holder

For the definition of disposable_cup_holder in the wiki, none of the posts with holding_disposable_cup_holder are "disposable cup holders". It's all disposable drink trays/boxes and cardboard sleeves.

I think post #4019111 and its child are the only posts under either of these tags with actual disposable cup holders. Does disposable_cup_holder really need to exist? I feel like the name is really confusing.

post #9360755 immediately stood out as wrong and I found it just from the wiki page without opening up the post results. These are still in essence cups, just that they're holding a disposable cup instead of the liquid directly, so the holding tag at the very least doesn't really need to exist, it's too granular.
