Horses stay still!

• 25w03a broke the datapack. But it also made it compatible with ALL entities, not just those that look like horses!

• So now compatible with all entities that can be ridden with saddles. (25w03a and beyond ONLY!)

• Added compatibility with several versions of MC so you can use it on 1.21 even if the new syntaxe isn't compatible.
• The horse will no longer be forced to stand still even after uninstalling the datapack!
