Pale Garden doesn't show up

Hi. When the snapshot for 1.21.2 came out, I played it to see the new pale garden biome, but it wasn't there. I tried to use the command of locate biome, I tried to search the items that came with the update, but none of the pale garden items would show up. 

I thought it was a snapshot bug or something, so I waited until the release to see if it worked. Nothing changed. I can't locate the pale garden by commands, there's none of the items found there in the creative mode and even if I use a seed where the garden is supposed to be, it's still not there. 

What do I do? I really want to play the update but I can't access the new biome.
