Record Components:
biomes - Biomes to add features to.
features - PlacedFeatures to add to biomes.
step - Decoration step to run features in.

public static record BiomeModifiers.AddFeaturesBiomeModifier(HolderSet<Biome> biomes, HolderSet<PlacedFeature> features, GenerationStep.Decoration step) extends Record implements BiomeModifier

Stock biome modifier that adds features to biomes. Has the following json format:

 {
   "type": "neoforge:add_features", // required
   "biomes": "#namespace:your_biome_tag" // accepts a biome id, [list of biome ids], or #namespace:biome_tag
   "features": "namespace:your_feature", // accepts a placed feature id, [list of placed feature ids], or #namespace:feature_tag
   "step": "underground_ores" // accepts a Decoration enum name
 }

Be wary of using this to add vanilla PlacedFeatures to biomes, as doing so may cause a feature cycle violation.
