Allay's head does not rotate to where it looks
The allay looks up and down as well as side to side but its head doesn't rotate up and down visually. It can also lag behind in horizontal rotation in some situations.
I presume it's because the head of the allay isn't its own model part, but rather part of the body, and uses body rotation instead of head rotation, but I haven't looked at the code.

The Bug
Relates to MC-250295, a similar issue that happened to Allays when they were first introduced.
The Vex's new model's head does not rotate to where it is looking, despite both the Allay and the old Vex model being able to do so, as seen in these images:

Old Vex model rotating its head

New Vex model unable to move its head despite looking to the side
------------------------------------------------------------------------------
Steps to reproduce:
- Summon a Vex, and watch them fly around.
- They will not turn to look at anything
- Enable hitboxes to see their line of vision; although they technically are looking around, their head does not rotate.
