www/ruby-rouge: update to 3.2.1

3.2.1: (2018/08/16)

https://github.com/jneen/rouge/compare/v3.2.0...v3.2.1

* Perl Lexer
  o Allow any non-whitespace character to delimit regexes (#974 by dblessing)
    - Details: In specific cases where a previously unsupported regex
      delimiter was used, a later rule could cause a backtrack in the regex
      system. This resulted in Rouge hanging for an unspecified amount of
      time.
