Copper golem saddle slot only accepts saddles and air

The saddle slot for copper golems only accepts the air and saddle items, when instead it should accept air and poppy (and preferably other items for consistency with other snapshots)

Reproduction

• Spawn a copper golem

• run
  /item replace entity @e[type=minecraft:copper_golem,sort=nearest,limit=1] saddle from entity @s weapon.mainhand
  while standing near it and holding any item

• observe

Expected result

Either:

• The copper golem accepts the item if and only if it is a poppy or air (L option)

• Or preferably the copper golem accepts any item, as A: previous snapshots allowed any item into what is now the saddle slot and B: its funner this way

Actual result

• Unless the held item is a saddle or air, the command throws an error that the slot didn’t accept the item
