Normally, if you kill zombified piglins in one hit they won't get mad at you because they can't call on the others nearby. However, if the zombified piglin who was killed in one hit spawns a reinforcement as it dies, it will be angry at you and anger all the other piglins nearby. This is counterintuitive and makes killing them in 1 hit pointless if it can just anger them anyway, even if indirectly. Note that this behaviour happens even in creative mode (MC-64087).

This was not the case before 1.21.2 because zombified piglins could not spawn reinforcement zombified piglins.

Steps to repproduce:

1. Set your difficulty to hard
2. Kill zombified piglins in one hit with a Smite V netherite axe.
3. A reinforcement spawns and gets angry at you. Depending on the local difficulty this can happen either instantly or in dozens of zombified piglins.
4. All the other piglins also get angry at you.

Observed results

When a zombified piglin reinforcement is spawned, it angers all zombified piglins nearby on you, even if you killed the caller in one hit.

Expected results

Zombified piglins wouldn't get angry at you for killing them in one hit per MC-2432 being resolved as Intended.
