v1.4.0 PLUGIN Release Candidate 2 for Bukkit, Spigot, Paper & Purpur

I apologize in advance to everyone who was unable to test the plugin due to the incompatibility caused by Adventure on Bukkit and Spigot servers :c

If everything goes well, the next version will be the initial release

• Fixed Adventure dependencies have been fixed, it should work correctly on Paper servers.
• Fixed bug where the plugin could not be loaded on Bukkit and Spigot server.
• Adjustment so that the plugin does not crash on non-Paper servers.
• Cleaned code.
