New enchants

Enchant #1: Fireproofing

This enchantment would make any item resistant to burning in lava or fire, like netherite.

Enchant #2: Make an item never despawn (call it whatever you want)

After dying or dropping an important item on accident, I always seem to just miss the despawn time of 5 minutes. This enchant would make any item not despawn.

Enchant 3: Curse of the void

When dying in the void or dropping an item, instead of items disappearing, the item will reappear at spawn, and if the item has the "never despawn" enchant, it will never despawn from spawn.

To make these enchants less overpowered, you guys can make each have a set amount per world. (e.g. for the fireproofing enchant, have it only spawn in only 5 nether fortresses in a world, so it encourages players to not waste these precious enchants.
