add FAQ about feedback, improve contact, update bin/status2html.sh

We added FAQ 0.5 about how to make a suggestion on IOCCC rules, guidelines and tools.

We added a mastodon tag for _contact.html#mastodon_.

We made a minor improvement to bin/status2html.sh about when
the IOCCC is open for submissions.

Changed `bin/status2html.sh` VERSION from "1.1.2 2024-03-26"
to "1.1.3 2024-04-12".

TODO: Complete content that hinted at by what is currently broken links.
      We pushed this change thru on the FAQ now, because we were aware of
      others wishing to submit a FAQ related pull request.
