The new Dripstone Caves biome is not appears to not be spawning. I am unable to locate it using /locatebiome, and cannot find it using spectator mode.

What I expected to happen was...:
I expected to be able to use the /locatebiome command to find the new Dripstone Caves biome.

What actually happened was...:
The /locatebiome command, when using the autofill for the Dripstone Caves biome, yielded a result reading: **Could not find a biome of type "minecraft:dripstone_caves" within reasonable distance. Additionally, the Dripstone Caves biome appears to not spawn naturally at all.

Steps to Reproduce:
1. Use the autofill for the command /locatebiome
2. Type dr and then hit Tab to autofill the target biome(minecraft:dripstone_caves)
3. Upon running the /locatebiome command, the normal result does not occur, instead, the output for the command reads Could not find a biome of type "minecraft:dripstone_caves" within reasonable distance. This does not change when the player moves into new chunks.
