DimensionPause

Thank you to @robinhickmann on GitHub for his work in putting this version together!

• Validates support for up to 1.21.8
• Fixes bugs
  • Toggling end having no effect when nether is paused
  • Being able to join a world that's paused, that previously wasn't when leaving
    • If a player is teleported in this scenario, they will not be alerted of this. Alerts will be added in a future release.
