Creakings cannot rotate their heads independently from their bodies

The Bug:

Creakings cannot rotate their heads independently from their bodies.

If a creaking wants to rotate its head, its body will always move with its head. While this design feature is okay, it's largely inconsistent with other hostile entities such as blazes, zombies, skeletons, creepers, spiders, etc.

Steps to Reproduce:

1. Summon a creaking and equip a carved pumpkin on your head and observe its behavior for around one minute.

2. Pay close attention to the rotation of its body and head and it changes directions.

Observed Behavior:

Creakings cannot rotate their heads without moving their bodies, which is largely inconsistent with other hostile entities.

Expected Behavior:

Creakings would be able to rotate their heads independently from their bodies.
