Add the auto-generated node catalog to the website's user manual (#3662)
* Generate the MVP node catalog in the manual (with some placeholders) * Implement nearly the rest of everything * Move to the tools directory and make it generate nicer default values * Add category descriptions * Organize file structure and improve type naming * Improve book table of contents code * Add collapsing chapter navigation to the book template * Add to build workflow * Clean up site structure
