The Enchantment damage increase API added previously used the EntityCategory enum as a parameter. These values are now however determined by tags instead of the categories themselves. Deprecated the outdated api method, create a new overload that takes EntityType instead and implement deprecated method by guessing an entity type from the builtin registry based on the category passed. This method allows a) the tags to still be modified and the legacy method still respecting such. b) potential cursed implementations of enchantments of plugins to not break that override the getDamageBonus method on Enchantment.
