Removes some damage sources to animals, and named animals (including allays) never take damage.
Specific changes:
- Axolotls don't "dry out" - they don't take damage from being out of water for too long.
- Bees ONLY take damage from players and other mobs. In particular, they won't take damage from water.
- Water animals do not "drown" when out of water.
VERSION 1.21.3 AND LATER:
- Make animals damageable again by naming them "killable"
