Change "Display in Mushroom Biomes" toggle to include all non-hostile biomes

[Owehttamy]

Currently, the toggle doesn't include the Deep Dark biome or account for non-hostile spawning biomes added with custom world generation data packs.

Of course, the custom biome aspect may be more of a hurdle that's not worth enduring, but it would only make sense to include the Deep Dark biome to the toggle as hostile mobs cannot naturally spawn in the biome.
