Zombified Piglins should be cureable

I'm not sure about keeping piglins immune to zombifying in the overworld, but zombie piglins should be cureable. Maybe with a splash potion of fire resistance or slowness and a golden apple? Curing a zombie piglin should cause it to never despawn and stay neutral, and not become hostile to the player unless directly attacked, unlike normal piglins who get mad super easily. However, because the piglin is still affected from the condition it previously had, instead of loving gold it should give gold to the player for things. When the player tosses it various items, such as maybe things like books, arrows, gunpowder, etc. the piglin has a small chance of tossing a gold nugget or ingot back.
