[Bedrock Parity] Visual Snowy Leaves

Added

• Resource pack workaround: set a tinted block model face tintindex to a nonzero value to be excluded from "snowification" (under the hood changes to the loaded texture where the biome colours are adjusted to account that)
  • This is likely use in compatibility resource packs for the actual packs
• Provided resource pack to fix vanilla Jungle Leaves "fruit" being "wrongly" tinted, (only available with Fabric API installed, specifically the fabric-resource-loader-v0 module)

Changed

• Snow leaves to be more snowier! Closer to MCBE.
