These changes merely replace "external" links with links to our "Normative References" appendix, thus completing the appendix:

• localBiblio added for external references that weren't in the Specref database
  • Note: these will be removed in future pull requests.
• links to References appendix are now underlined: a.bibref { text-decoration: underline;}
• "plain markdown" external links have become links to the References appendix, for example
  • old: <a href="https://www.iana.org/assignments/http-status-codes/http-status-codes.xhtml">IANA Status Code Registry</a>
  • new: <cite><a class="bibref" data-link-type="biblio" href="#bib-iana-http-status-codes" title="Hypertext Transfer Protocol (HTTP) Status Code Registry">IANA Status Code Registry</a></cite>
• first mention of "JSON" and "YAML" formats are now bibliography links
• Normative references have been added for
  • ABNF
  • CommonMark
  • IANA Auth Schemes registry
  • IANA HTTP Status Codes registry
  • JSON Schema draft specification (version depending on OAS version)
  • SPDX Licences List

@OAI/tsc Second review please, the diffs are not going to get smaller with the next changes to the build script, easier to review them chunk by chunk 😁
