refactor plugin

[Mapacheee]

Hi! This is a refactor of EasyJoin to support lastest versions (1.21.x) and made with WinterFramework.

This includes new features as:

Avatar

[AVATAR_MESSAGE] &aWelcome to the server!<nl>&7%player_name%<nl>&bEnjoy your stay!

Sound

Now [SOUND] support SpigotMC & PaperMC API, so you can use custom sounds of texturepacks too!

- '[SOUND] ENTITY_PLAYER_LEVELUP;1;1'
- '[SOUND] minecraft:entity.player.levelup;1;1'
- '[SOUND] someplugin:custom.sound;1;1'

Folia Support

EasyJoin now works in PaperMC and Folia (and their forks)!
