www/ruby-loofah: update to 2.21.2

2.21.0 (2023-05-10)

HTML5 Support

Classes Loofah::HTML5::Document and Loofah::HTML5::DocumentFragment are
introduced, along with helper methods:

* Loofah.html5_document
* Loofah.html5_fragment
* Loofah.scrub_html5_document
* Loofah.scrub_html5_fragment

These classes and methods use Nokogiri's HTML5 parser to ensure modern web
standards are used.

⚠ HTML5 functionality is only available with Nokogiri v1.14.0 and higher.

⚠ HTML5 functionality is not available for JRuby.  Please see this upstream
Nokogiri issue if you're interested in helping implement and support HTML5
support.

Loofah::HTML4 module and namespace

Loofah::HTML has been renamed to Loofah::HTML4, and Loofah::HTML is aliased
to preserve backwards-compatibility.  Nokogiri::HTML and Nokogiri::HTML4
parse methods still use libxml2's (or NekoHTML's) HTML4 parser.

Take special note that if you rely on the class name of an object in your
code, objects will now report a class of Loofah::HTML4::Foo where they
previously reported Loofah::HTML::Foo.  Instead of relying on the string
returned by Object#class, prefer Class#=== or Object#is_a? or
Object#instance_of?.

Future releases of Nokogiri may deprecate HTML classes and methods or
otherwise change this behavior, so please start using HTML4 in place of
HTML.

Official support for JRuby

This version introduces official support for JRuby.  Previously, the test
suite had never been green due to differences in behavior in the underlying
HTML parser used by Nokogiri.  We've updated the test suite to accommodate
those differences, and have added JRuby to the CI suite.

2.21.1 (2023-05-10)

Fixed

* Don't define HTML5::Document and HTML5::DocumentFragment when Nokogiri is
  < 1.14.  In 2.21.0 these classes were defined whenever Nokogiri::HTML5 was
  defined, but Nokogiri v1.12 and v1.13 do not support Loofah subclassing
  properly.

2.21.2 (2023-05-11)

Dependencies

* Update the dependency on Nokogiri to be >= 1.12.0.  The dependency in
  2.21.0 and 2.21.1 was left at >= 1.5.9 but versions before 1.12 would
  result in a NameError exception.  [#266]
