Cod, salmon, puffer fish and tropical fish can be catched into a boat

This issue relates to MC-125218 / MC-126023.

This isnt a bug since its programmed to do that like any other animal.

I disagree with that, ocean/water/swimming mobs shouldn't enter a boat, see MC-89985.

@unknown, with exception of guardians and elder guardians, as they can spawn only in ocean monuments.

is this really WAI? fishes no longer enter boats. It was decided that dolphins sitting in boats isn't intended, which is contradictory. https://bugs.mojang.com/browse/MC-128241
