docs: README pass, add alternative editor documentation (Zed) (#4137)

I'm switching away from visual studio (because its broken) so figured
I'd document / commit the minimum to get a working environment with the
editor I chose (Zed).

Also cleaned up the main README so it's not so verbose, link out to
secondary pages, etc.

I also deleted the Arch and Fedora dockerfiles, they were broken. The
ubuntu one still works, so i left it.

+This will create a `jak-project` folder, open the project as a CMake project via Visual Studio.

+Then build the entire project as `Windows Release (clang)`. You can also press Ctrl+Shift+B as a hotkey for Build All.  We currently prefer `clang` on Windows as opposed to `msvc`, though it should work as well!
