Feature/lua api autogen

[cscheid]

This PR uses the output of Lua-LS --doc to auto-generate API documentation.

Structure:

• _*.md files are automatically generated by quarto run tools/build-lua-types-autogen.ts
• _*.qmd files include the associated _*.md file, and can add additional hand-written material to the top of the document (see docs/lua/quarto/brand.qmd for a minimal example)
• if the tools/build-lua-types-autogen.ts script is run with stubs as the first parameter, it will overwrite the .qmd files in docs/lua.
• all files in this directory run with the docs/lua/luaapi_autogen.lua filter which drops some bad markdown generated by Lua-LS.
