devel/ruby-activemodel52: add version 5.2.2 package

Add ruby-activemodel52 version 5.2.2 package.

Active Model provides a known set of interfaces for usage in model classes.
They allow for Action Pack helpers to interact with non-ActiveRecord models,
for example. Active Model also helps building custom ORMs for use outside of
the Rails framework.

This is for Ruby on Rails 5.2.
