Allay's lead hold position is incorrect

Steps to Reproduce:

1. Use a lead on any leashable mob

2. Attach it to an allay

Observed Results:
The leash connection moves relative to the head instead of the body. This means it’ll float under its head for most of the time, since the allay’s flying animation rotates its body.

Expected Results:
The leash is connected to the allay’s body, adapting to its animations accordingly.
