Nether's bane enchantment

This would be a new enchantment that could be gotten only in piglin bastions or by bartering The enchantment would damage any mob that naturally spawns in the nether like blazes, wither skeletons, endermen, skeletons, piglins, etc. It would also do less damage to overworld mobs (excluding skeletons and endermen) and post enderdragon mobs.
