Ruby ci-queue requires gems that are not runtime dependencies

We are getting LoadError: cannot load such file errors from the ci-queue ruby gem when trying to use it. It looks to me that the gem specifies several development_dependencies but uses them outside of development at runtime.

The fix on our end is to require this gems dependencies in our gemfile. The gem should properly specify its dependencies so installing it via bundler will grab everything it needs.

Here are the errors I've encountered:

Start with lib/ci/queue/redis.rb and lib/minitest/queue.rb, then inspect the gem's dependency declaration to compare the required redis and minitest/reporters libraries with Bundler's runtime set. Run the minitest-queue entry point without manually added dependencies; done means it loads successfully and no longer raises either reported LoadError.
