Configured Feature Saplings - Fix for Datapack Compatibility

This mod resolves the issue that prevents datapacks from properly configuring generation features that grow from saplings and mushrooms. This bug was recorded under number MC-251744 in Mojang's official tracker.

Simply put, you can now edit files in the worldgen/configured_features folder through datapacks, and all changes will correctly apply when growing trees from saplings or mushrooms. In the standard version of Minecraft, such modifications only work when generating new chunks, while manual cultivation always uses hardcoded vanilla features.
