The model of juvenile zombies/drowned corpses/corpse shells is misaligned and mismatched in size after wearing helmets

Reproduction Steps:

1. Switch the time to night.

2. Use spawn eggs to generate wearable equipment juvenile zombies, juvenile drowned, and juvenile husks.

3. Throw any helmet at them and make them wear it.

Actual Result:

After juvenile zombies, drowned, and husks wear helmets, the helmet model does not fit the head properly, the size does not match the head, and rendering is abnormal.

Expected Result:

After juvenile zombies, drowned, and husks wear helmets, the helmet model should fit the head closely, with normal proportions and appropriate size.
