Add Support Folia

[Euphillya]

Information

This PR replaces #5291.

Details

Proposed feature:
I'm proposing full Folia support for Essentials.

To avoid breaking Spigot/Bukkit, I've added classes so you can use either:

• Bukkit schedulers
• Folia schedulers

However, I've disabled the tps function in /gc because in Folia, you can add it by iterating through the TPS of each chunk and providing information similar to Folia's /tps function, such as the highest, lowest, and median TPS.

I haven't made the modules compatible yet, as I'd like your initial feedback on whether to continue in the same direction or not.
