Update the gemfiles/rails_5_2.gemfile to point to 5.2 stable and the build will be fixed.

The 5-2-stable branch: contains a gemspec which says ">= 2.2.0" required_ruby_version. Its last commit is "prepare for 5.2.4.1 release". Seems like safe navigation (a 2.3+ feature) has crept in without a bump to required_ruby_version in the gemspec..

I was hasty in my reading. A PR which does what was suggested works. Thanks!
