MCBuild Port

• Upgrade and fixing the datapack to work with mcbuild, allowing for easier developing!
• Now I'll start use a more proper semantic versioning so format like vX.Y.Z-A:
  • X: major version, backward incompatible
  • Y: minor version, backward compatible (unless said so)
  • Z: patch version, backward compatible (usually bug fixes)
  • A: pre-release version (this datapack it's still on alpha so will basicaly only be alpha for now)
• Balloons no longer need empty hands to be seated on
