Slope biomes for warm areas

The first experimental snapshots of 1.18 introduced the ability for biomes to generate on hills and mountains without the need of a similar biome for that purpose. 6 new mountain biomes had been added, but the slope biomes for warm areas are missing. Stony slopes (barren surface without dirt), scrubs (occasional oak trees few and far between, with only coarse dirt and gravel, in drier areas), the classic pre-Caves and Cliffs wooded mountains, and the dense cloud forest (generates near jungles, at y=120-210, directly bordering the stony slopes/peaks or even lofty peaks, only exist on super mountains where their peaks are at y=220-260, occasionally y=300)
