Jakarta Standard Tag Library 3.0.0

The plan for the release is to clean up open issues:

•  General specification document cleanup.
• Clean up issues found during the Jakarta EE9 review ballot process: update if possible the tagdocs to include EFSL, Update tlddoc generation if possible to jakarta.
• Remove any deprecated methods from the API.
• Rename java.sun.com / xmlns.jcp.org taglib URIs to new jakarta.tags.\* URNs.
  • This alone should require a major release.
• Other small clean up issues
