fix: Set bad exit code on error

[LukasHechenberger]

Otherwise CircleCI does not fail on bad commit messages

@LukasHechenberger I came here just because of this issue, seems the plugin is useless without your change.

In the mean time you can achieve pretty much the same result (without this dependency) by doing the following in your .circleci/config.yml

      - run:
          name: Commit lint
          command: ./node_modules/.bin/commitlint --from origin/master --to ${CIRCLE_SHA1}

I hope this gets merged though 🤞

You can also use my fork in the meantime, it's available on npm as @ls-age/commitlint-circle.
