Modern Beta [Fabric]

This release features many changes, including the re-implementation of an in-game world customization GUI, so the major version has been bumped to 6. Worlds created on versions 5.x are compatible, but please create a save back-up first if you wish to upgrade.

Changes:
* Removed option isleCenterIslandFalloff and replaced with new option isleCenterIslandFalloffDistance, where you can specify the main island-ocean transition distance in chunks instead of an arbitrary float value.
* Removed option islesMaxOceanDepth and replaced with new option islesOceanSlideTarget.
* Updated some biomes to add/remove mobs.
* Updated deep cave carver to improve generation variety.
* Reworked organization of visual configuration options.

Additions:
* Re-added an in-game world customization GUI. The GUI has been reworked compared to previous releases:
* You can select from multiple world presets for basic terrain generation types (Beta, Alpha, Infdev, etc.). If you hold down the Alt key while cycling through presets, you can select other weird and fun presets.
* Selecting "Settings" for Chunk, Biome, and Cave Biome settings will open a screen with a box containing the JSON settings. You can edit this in-game or copy/paste the whole block into a text editor of your choice.
* Added chunk generation options useCaves and indevUseCaves, which toggle regular carver and Indev carver generation, respectively. The indevUseCaves option only works on Indev worlds.
* Added chunk generation option isleCenterIslandShape, which controls the shape of the main island when generating island worlds. The available options are "circle", "square", and "diamond".

Removals:
* Removed the Cloth Config files for chunk, biome, and cave biome generation options. Default world generation options are completely contained within Modern Beta's world preset file (can be found and edited in the data pack). Further customization of world settings should be done in the in-game world customization GUI or separate data pack.

Fixes:
* Fixed voronoiDepthMinY and voronoiDepthMaxY not being saved to level NBT.
* Fixed an issue where snow/ice would sometimes not properly generate due to the mix of Beta/vanilla biomes.
* Fixed deepslate generation not working on Infdev 227 worlds.
