+solidus_i18n Version 2.0+ only contains translation files.

+Previous versions of solidus_i18n included extra functionality like locale
+selectors and which is now built in to Solidus 2.6+. Configuration for

 gem 'solidus_i18n', '~> 2.0'
+gem 'rails-i18n', '~> 5.1'
+gem 'kaminari-i18n', '~> 0.5.0'
