Convert old player leaves into new system
This commit adds a couple of lines to the `mcl_mapgen_core:fix_foliage_palette_indexes"` LBM, which ensures that player leaves which were placed before this update get converted into the new player leaves. I would have included mangrove leaves, but decided against it because of an issue where the `param2` of mangrove leaves was accidentally set to 1 (in the schematics?). This meant that if I included mangrove leaves, the LBM would have converted the natural leaves as well. This would have made it very tedious to clean up the leaves after chopping down a mangrove tree, since these would not rot by themselves.
