Allow dragons to slowly regenerate by themselves

[MollyLovesReptiles]

It would be really cool if dragons were able to regenerate by themselves like horses.

yeah!

And, it could work even on wild dragons, making fights interesting! If they kill you, when you come back, they are healthier!

Perhaps they still need to eat, but like the player, they have a hunger bar, refiled by eating animals and villagers (and food if tame). Would explain why they fly out!

Larger dragons are "so large they can store enough food to regenerate almost forever" (A.K.A. an explanation as to why large wild dragons continue to regenerate, even without food. The non-wild ones, as you raised them, have a "smaller stomach". Yeah

In my datapack, I gave the ender dragon regeneration for this exact reason, so yea, this is a good idea.
