The former FAQ 0.0 section in `faq.html` now just refers to `quick-start.html`.

Modified menu and non-JS menu so that "Enter the IOCCC" refers to `quick-start.html`.

Changed `bin/gen-top-html.sh` VERSION from "1.4.10 2024-11-23"
to "1.4.11 2025-01-09".

Performed `make www` on macOS to complete the above.
