Generate documentation from comments

[goldenstein64]

I'm not 100% happy with LuaLS's doc generation capabilities, mainly because it also documents all Lua globals.

The current plan is to process the JSON file it produces and turn it into the documentation I want using some kind of template format, e.g. using something like leafo/etlua.

Looking at LuaLS's changelog, v3.10.6 added a setting for generating user-specified doc exports, Lua.docScriptPath. If I ever get stuck trying to find something, I may have to fork their script.

I currently have a blocker: I'm using lua:// links in my documentation, and I will somehow need to convert that into a location in the docs, which seems non-trivial given the amount of freedom I have in structuring my docs. I might try manually writing a mapping from lua:// to links relative to the project root that refer to the right .md file and fragment.
