Quite a lot of changes, but I was too lazy to split them in different commits (and they'll be squashed later anyway):
* Floodgate plugin message channels are now registered (because Spigot requires that, and I guess it's better practice)
* Updated the Statistics form to match the new Forms API
* The common jar is now much smaller, because Jackson isn't needed anymore in the common module
* Fixed some bugs in Forms where empty fields would lead to excluding them in the serialization (making Bedrock complain)
And a few other things, like a new boolean in RawSkin saying if the Skin is an Alex or Steve model.
* Change versioning to match supported Bedrock version
Line up Geyser's versioning to match with the highest/currently supported Bedrock version for future tracking of older Geyser versions.
* Add version command
* Fix DEV check for version command
* Remove SNAPSHOT
* Update languages submodule
