Piglins drop their previous gold armor/weapon on the ground instead of keeping it away in their inventory

The bug

If a piglin switches its current tool/armor to an enchanted one, they'll drop their old item into the ground, and inspect their old weapon/armor again rather than putting it away in their inventory.

This works with piglins that already has gold armor/swords.

To reproduce

1. Spawn piglin
2. Give it an unenchanted golden tool/armor
   → The piglin inspect it and equips it
3. Give the piglin an enchanted golden weapon/armor
   → The piglin drops the unenchanted gold armor/weapon into the ground, and then picks it up again, inspecting their old tool/armor and puts the item in their inventory.
