devel/ruby-activemodel60: add package version 6.0.2.2

Add ruby-activemodel60 package version 6.0.2.2.

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 6.0.
