docs: byline and licenses for the 3.13.0 post

- author and date below the title, styled as .nj-byline; its link gets
  no external-link icon
- the license of every library in the thanks section, checked against
  each project's license files; credit sonic-rs for QUOTE_TAB, which
  orjson adapted from it
