Updates to support MC 1.21 and up.
- Includes missing paintings and remove Spigot compatibility issues/fix deprecations
- Changes WorldGuard to a soft dependency so worlds aren't required to use it
For those running MC <1.21, consider still using v2.0.0 and if you run into issues, [open a new ticket on GitHub](
