Dolphins can sit in boats

This is just funny! XD

I realize the resolution to the corresponding bug report about turtles getting into boats was that if it fits it sits, which is fair enough normally. The difference between all other mobs that get into boats and dolphins is that dolphins can't breathe when in a boat so they die. Combined with their love of jumping onto land and dying there, the results are quite heartbreaking.

Also relates to MC-89985

Turtles getting into boats might be intended but dolphins may not.

You can even have 2 turtles in the same boat and they look like conjoined twins, I think it's a bug

Turtles are working as intended, but fixed issue with dolphins so they will no longer sit in boats.
