hello, it seems that the warden attacking zombie pigmen will not cause the pigmen's aggression to trigger.

Expected:

 When a warden inflicts damage or kills a zombie pigmen, the other pigmen nearby should gain aggression towards the warden.

Actual:

 When a warden inflicts damage or kills a zombie pigmen, the pigmen do not gain aggression.

Tested on:

Minecraft 1.20.1, Java 17 64-bit, Ubuntu.
