Describe the bug

Created a datapack in location, decided to tweak oil lake gen
(was loading recipes before and they're working fine)
\config\paxi\datapacks\litiv2-datapack\data\pneumaticcraft\tags\worldgen\biome\has_surface_oil_lakes.json

that contain only:

{
  "values": [
    "#minecraft:savanna"
  ]
}

And can't find any oil lakes in savanna. This was tested with default world gen, with no added mods.
With my file: (completely no oil lakes, but they should generate only in savanna)

Without: (you can see oil lakes, even in savanna biome)

How to reproduce the bug

Try to create datapack that limits oil lake gen to certain biomes

\config\paxi\datapacks\litiv2-datapack\data\pneumaticcraft\tags\worldgen\biome\has_surface_oil_lakes.json

{
  "values": [
    "#minecraft:savanna"
  ]
}

Expected behavior

Oil lakes to generate only in specified biome (savanna)

#savanna isn't a valid biome tag. I think you meant to use #is_savanna here.
