use base collect/remove for item link groups

How was this tested?

not in the slightest, not even sure what the get part does to be honest

If this makes graphical changes, please attach screenshots.

In favor of this. Anything that doesn't work with this is a bug itself, imo

Doesn't work...

  File "F:\Archipelago\worlds\AutoWorld.py", line 509, in collect
    name = self.collect_item(state, item)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: World.collect_item() missing 1 required positional argument: 'item'

:( Idk how to make it work

[NewSoupVi]

Turns out the classmethod might not be necessary

Yeah this works I think
