Mod update to work on version 1.21.2 and 1.21.3.

Along with updating the mod, this update also addresses some existing issues with cooldowns.

Changes

• Updated to 1.21.3 Minecraft.
• Parry and Lunge now change the cooldown group of the enchanted item.
  • Parrying an attack will put all items with parry on cooldown and only those items.
  • Lunging works similarly, putting all Lunge weapons on cooldown.
  • Items without either of these enchantments are unaffected.
• Parrying and attack will now apply the maximum cooldown, as if you had held the weapon out for too long.
• Offhand damage no longer uses mixins and now makes use of Fabric API for improved compatibility.
