Scute items from a baby turtle growing up are spawned too high

Scutes spawned from a baby turtle when they grow up will be positioned too high above the entity.

Steps to Reproduce:

1. Tick freeze the game for observation:

   /tick freeze
   

2. Summon a turtle 1 tick away from growing up:

   /summon minecraft:turtle ~ ~ ~ {NoAI:1b,Age:-1}
   

3. Advance the game by 1 tick

   /tick step 1
   

Observed Behavior:

The scute will be positioned too high above the turtle entity.

Expected Result:

The scute would be positioned directly above the top of the turtle when it grows up, similar to other items created from entities by game events/interactions.
