add missing author/index.html

We changed `author/README.md` to refer to FAQs instead
of trying to duplicate FAQ information.

Added `author/README.md` to `bin/md2html.cfg`.

Changed `bin/gen-top-html.sh` VERSION from "1.4.8 2024-08-05"
to "1.4.9 2024-08-11".

Performed `make gen_top_html` to accomplish the above and to test under macOS.

bin/gen-top-html.sh
