[v3.6.0] A big update

This release has really a lot of improvements, fixes and a few additions.
A lot of code has been re-written and improved. A lot of bugs have been fixed.

Most important changes:

• New option: Added option for servers with multiple scoreboard/rank plugins that might fix some issues. (scoreboard-advanced-settings.use-existing-scoreboard)
• New option: Because lots of users wanted to use HEX colors for the player name in the tablist, you can now do that by enabling 'ranks.options.show-suffix-in-tab' and optionally 'ranks.options.use-player-list-name' to preserve the prefix & suffix above the player's head (where possible).
• Improved: The LuckPerms weight limit has been lifted from 999 to 9999.
• Improved: Added descriptions to the PowerBoardAPI (for developers).
• Fixed: The SelfCheck has been reworked and now also checks the config in older MC versions. In the versions 1.18+ it also automatically adds and corrects missing options.
• Fixed: An update check will now be performed every 24h.
• Fixed: Ranks updating too often when not needed
• Not fixed in code but randomly started working again: HEX colors no longer count as (14) chars. This means long HEX color gradients are now possible!
• As a bonus: The plugin jar has lost a quarter of it's size!

Also big thanks to @ItsLaivy and @itsTyrion for your PRs! These helped me a lot and gave me some motivation!
