The spawn eggs for the zombie horse, the skeleton horse, the mule, and the donkey are named incorrectly.

I think that the eggs should be named: "Spawn Zombie Horse", "Spawn Skeleton Horse", "Spawn Mule", And "Spawn Donkey"

What I saw was the eggs named: "Spawn entity.ZombieHorse.name", "Spawn entity.SkeletonHorse.name", "Spawn entity.Mule.name", and "Spawn entity.Donkey.name"

Steps to Reproduce:
1. Open up the creative inventory.
2. Go to the "Miscellaneous" tab.
3. Scroll down to the "Spawn Zombie Horse", "Spawn Skeleton Horse", "Spawn Mule", and "Spawn Donkey" eggs.
4. Hover over the eggs.
