Forge 1.20

- Creative mode tabs are now a registry; the `BuildContents` event was renamed to `BuildCreativeModeTabContentsEvent` and moved it to its own class
- The pack format is now 15 for both resource packs and data packs
- `ScreenUtils` was deprecated in favor of a `GuiGraphics` extension
- Forge and the MDK were updated to Gradle 8 and FG6
- The Forge common config file was removed (it only contained the deprecated old fields for resource caching, which was removed in 1.19.3)
- Registry dummy entries were removed
- `RemappingVertexPipeline` was fixed to forward the `endVertex()` call
- Forge tool tags were removed in favor of vanilla ones
