New PC mod dev wiki

[qqrz997]

finally, it's here!

Complete revamp of the original modding wiki. JetBrains Rider becoming free for non-commercial use has made Rider a very compelling option for PC modding, and since the modding tools extension for Visual Studio isn't being maintained any more, this new Rider-focused wiki has come at an important time.

This wiki not only updates the setup page. It comes with a slew of new pages, each covering an important topic related to modding on PC:

• A section covering installing Runtime Unity Editor to inspect objects in-game
• A section about decompiling Beat Saber's code using ILSpy
• A short selection of Harmony patch examples
• A large introduction to BeatSaberMarkupLanguage
• A page covering SiraUtil's various APIs and introducing Zenject
• And finally, a whole written tutorial on making a functional mod from scratch

The modding index has been updated and a lot of the PC-specific information like launch args has been moved to the PC index.

This change also slightly reorganizes the modding directory of the wiki to better separate the PC and Quest pages.

All changes on the fork can be viewed here.
