[BUG] Turtle Growing Item (Baby -> Adult)

[PirataGu]

When turtles grow up (from baby to adult) in Minecraft they drop a Turtle Item (shell I think) but if they are multiple babies they do not drop more than 2x Shells which is the limit in minecraft for just 1x turtle I think.

This is also the behavior for baby armadillos, entities inside the stack do not age, and therefore should not drop items. Baby entities are set not to stack by default for this reason.

Worth noting, however, this is only true for NBT data storage. I could change it for SIMPLE data storage since all entities are just the main entity, though it could lead to issues where adult entities merge into a baby entity stack and drop items when they shouldn't. There isn't really a good solution besides not letting baby entities stack.
