www/ruby-loofah: update to 2.22.0

2.21.4 (2023-10-10)

Fixed

* Loofah::HTML5::Scrub.scrub_css is more consistent in preserving whitespace
  (and lack of whitespace) in CSS property values.  In particular,
  .scrub_css no longer inserts whitespace between tokens that did not
  already have whitespace between them.  [#273, fixes #271]

2.22.0 (2023-11-13)

Added

* A :targetblank HTML scrubber which ensures all hyperlinks have
  target="_blank".  [#275] @stefannibrasil and @thdaraujo
* A :noreferrer HTML scrubber which ensures all hyperlinks have
  rel=noreferrer, similar to the :nofollow and :noopener scrubbers.  [#277]
