app-text/ronn-ng: enable ruby31, enable ruby32; drop unnecessary man page build

- Enable ruby31, enable ruby32

  This only takes one patch and it's just for tests to work
  with newer psych. Fedora is just using that same patch too, no others.

- Drop unnecessary man page build. They're included in the gem,
  so we don't need to build it again (which causes a problem
  when invoking rake directly/calling unwrapped ronn, as e.g.
  nokogiri isn't necessarily installed for it anymore.)

+Subject: [PATCH] Workaround for Psych 4.0+ in tests
+
+Psych 4.0, shipped with Ruby 3.1, switched to a "safe load" by default, and requires you to explicitly set allowed classes. But previous Psych versions didn't support this kwarg, so the call needs to be made differently depending on which version of Psych/Ruby this is running under.
