Make channel 1-12-1 (mostly) Ruby 2.4 compatible (#295)

- Update plugins to the last Ruby 2.4 compatible versions.
- Be specific about the versions in Gemfile, so bundle update works.
- Do the bundle update.
- Don't downgrade ruby-i18n and ruby-graphql; the listed versions are
  not compatible with Ruby 2.4, so don't use them if using Ruby 2.4.

[Fixes #272, #291, #293]
