feat: add fine-grained biome control to Minestom world builder

Introduced a `doFineGrainedBiomes` flag to allow fine-grained biome control per chunk. This helps mitigate client disconnection issues caused by a Minestom biome encoding bug, with a plan to deprecate once the bug is resolved. Adjusted relevant classes and the example implementation to support this feature.
