`TreeFeature#updateLeaves()` Has Incorrect Parameter Names for its `Set<BlockPos>` Parameters

[voidsong-dragonfly]

Minecraft version: From 1.19.2 onwards according to the GitHub, but seen in 1.20.1 and 1.21.1
Mappings version: Tested in 2024.11.17, but the current github mappings still show the issue here.

In TreeFeature#updateLeaves(), the last three parameters listing Set<BlockState>(s) are incorrectly named. From testing in-game and from the logic, the sets are for the positions of:
2. The trunk
3. The decorations
4. The roots

In the Parchment parameter names, these are:
2. Set<BlockPos> rootPositions
3. Set<BlockPos> trunkPositions
4. Set<BlockPos> foliagePositions

The code also makes little sense with the Parchment mappings; with the current mappings it would seem to be scanning out from the roots to find leaves that are not already part of the tree in contact with the roots to update them.

In actuality, this code scans outwards from the trunk - ignoring the decorations and roots - to find leaves to update with their Manhattan distance from the logs.

I would suggest the parameter names for the three sets be, in order:
2. Set<BlockPos> trunkPositions
3. Set<BlockPos> decorationPositions
4. Set<BlockPos> rootPositions

As that would resolve the issue and make the parameters consistent with the other names used in the class.
