www/ruby-actionpack52: add version 5.2.2 package

Add ruby-actionpack52 version 5.2.2 package.

Action Pack is a framework for handling and responding to web requests. It
provides mechanisms for *routing* (mapping request URLs to actions), defining
*controllers* that implement actions, and generating responses by rendering
*views*, which are templates of various formats. In short, Action Pack
provides the view and controller layers in the MVC paradigm.

This is for Ruby on Rails 5.2.
