Log Message:
Update ruby-redcarpet to 3.2.2.

pkgsrc change:

* Add ${GEM_EXTSDIR}/gem.build_complete for new rubygems and updated ruby.

Version 3.2.2

* Consider script as a block-level element so it doesn't get included inside a
  paragraph.

Version 3.2.1

* Load RedcarpetCompat when requiring Redcarpet for the sake of backward
  compatibility.

  Loren Segal

Version 3.2.0

* Add a Safe renderer to deal with users' input. The escape_html and
  safe_links_only options are turned on by default.

  Moreover, the block_code callback removes the tag's class since the user can
  basically set anything with the vanilla one.

  Robin Dupret

* HTML5 block-level tags are now recognized

  silverhammermba

* The StripDown render object now displays the URL of links along with the
  text.

  Robin Dupret

* The RedCloth API compatibility layer is now deprecated.

  Robin Dupret

* A hyphen and an equal should not be converted to heading.

  namusyaka

* Fix emphasis character escape sequence detection while mid-emphasis.

  jcheatham

* Add = to the whitelist of escaped chars so it can be used inside highlighted
  snippets.

  jcheatham

* Convert trailing single quotes to curly quotes. For example, Road Trippin'
  now converts to Road Trippin¡Ç.

  Kevin Chen

* Allow in-page links (e.g. [headline](#headline)) when :safe_links_only is
  set.

  jomo

* Enable emphasis inside of sentences in multi-byte languages when
  :no_intra_emphasis is set.

  Chun-wei Kuo

* Avoid making :no_intra_emphasis only match spaces. This allows using
  emphasizes inside quotes when the option is enabled for instance.

  Jason Webb and BJ Homer

* The StripDown renderer handles image tags now.

Version 3.1.2

* Remove the yielding of anchors in the header callback. This was a breaking
  change between 3.0 and 3.1 as the method's arity changed.
