Baby piglins make hostile piglin noises, despite not being able to attack

Baby piglins make angry noises at the player even though they can't attack the player.

How to reproduce:
1. Spawn a group of piglins. One of them must be a baby.
2. Switch to Survival mode and attack the adult piglins. You can kill them to isolate the noises that the baby makes better.
3. Listen closely. The baby piglin(s) will angrily grunt at you, even though they don't actually ever get angry. I expected the baby piglins to make no angry grunts due to being passive mobs, but they grunt angrily anyway.
