The old (pre-Spring to Life) spawn egg texture is still used for no-data spawn eggs

Relates to MCPE-165289 and MCPE-190635.

If you run this command:

/give @s spawn_egg

the item you receive will be shaped like a pre-2025 spawn egg, despite this texture being entirely deprecated. This is wrong.

Expected results: this item would use the current chicken egg texture, or some fallback “generic” spawn egg texture.

Actual results: an old, removed texture is erroneously and unexpectedly still used.
