Cobblemon: Natural Spawning Tumblestone

Hey all! Anyone else wished tumblestone spawned natrually in the world? I know I did! Espically since i like to do small Roleplays with friends where we are in a legends arceus setting. However, there was no already established datapacks or mods from what I could see that did this. So, since I cant code to save my life. I turned to ChatGPT (I Know, gross) And got this made. Surprisingly it works really well. But then again it isnt anything to major like an actual mod so i guess that checks out.

Tumblestone spawns in caves at Y level 60 to 0.

Black tumblestone spawns at Y level 0 to -64

Sky tumblestone spawns in mountains at Y level 100 to World Height.

I originally just did this for me and my friends to play with, but i think i seen some people also talking online about wanting tumblestone as a thing to spawn natrually. So i figured id post it. If anyone else wants to make a mod or datapack like this without AI? Thats great. But for now, consider this a temporary thing untill someone does that.
