Make a nicer wiki

[mdsimmo]

What problem does the feature solve
The current wiki is ugly, doesn't support permalinks and sidebar is disorganized, and no good spot to upload images.

Describe the solution you'd like
Build a website (using github pages) that is nice.

Describe alternatives you've considered
Patch the wiki. But most problems cannot be fixed by patching.

Additional context
Inspired by lucky-perms wiki.
