Pure Berries

v5.0.0: Full refactor, ported to 1.21. Added redcurrant, blackcurrant, gooseberry, and cape gooseberry crops with unique biome placements. Added golden berries with five new effects: detoxify, luminance, nimbus, sustenance, and vitality. Effects are configurable via gamerule for potency tuning. Added new foods including golden berries and berry cakes. Renamed biscuits to cookies and tarts to pies. Added the mortar and pestle block with 13 variants, crafted via stonecutter (netherite via upgrade template). All nine berries can be crushed into dye using the mortar and pestle. Introduced glow dye from glow berries, mimics glow ink sac behavior. Updated textures for nearly every item and block, including major redesigns and minor color adjustments.
