Bow Infinity Fix

Updated to MC 1.21.x.

Due to Mojang changing enchantments to be datapack-driven now, this mod now checks if the enchantments applied to the bow/crossbow have a minecraft:ammo_use effect that reduces its value to 0, instead of directly asking if Infinity is applied. This should have the same effect by default, but now this mod should more easily work with other mods/datapacks (for example, if the stock Infinity enchantment is replaced with some other one, or a new enchantment is made that has infinity-like effects).
