fix(circleci): releasing to next

[tdeekens]

Summary

On CircleCI we currently attempt to release from master without a tag. Which fails as the previous version already exists.

Given this configuration:

workflows:
  version: 2
  build-n-deploy:
    jobs:
      - build:
          filters:  # required since `deploy` has tag filters AND requires `build`
            tags:
              only: /.*/
      - deploy:
          requires:
            - build
          filters:
            tags:
              only: /^v.*/
            branches:
              ignore: /.*/

• The build job runs for all branches and all tags.
• The deploy job runs for no branches and only for tags starting with ‘v’.
