[GH Repo] Fixed some stuff in the repository

[skManux]

What changed?

• Added logo and improved READMEs headers
• Deleted old documentation (Last commit was from 2 years ago)
• Fixed the "Localized READMEs" sections of all READMEs (Some did not have all the languages)
• Removed "Not Enabled" warning in the Analyzer Config
• Removed GettingStarted READMEs (Everything has been moved to the website)
• Updated logos with the new ones (I downloaded them from the website)
• Deleted other unused files

If possible, I would also like to get the Exiled Contributor role on the Discord server. My username is sk_manux.
