Add Test step for auto --dry-run

[mercillo]

During the test step in the circleCI config, add a step for auto dry run

          command: yarn auto shipit --dry-run

You will need to make sure a GH_TOKEN is passed, as running the command itself will give you an error

Make sure it is available on process.env.GH_TOKEN.
Error: GitHub token not found!
