Log Message:
Update to 0.0.27. From the changelog:

- Add way to configure `MOB_WIP_BRANCH_QUALIFIER` via an environment
  variable instead of `--branch` parameter. Helpful if multiple teams
  work on the same repository.
- Add way to configure `MOB_WIP_BRANCH_QUALIFIER_SEPARATOR` via an
  environment variable. Defaults to '/'. Will change to '-' in future
  versions to prevent branch naming conflicts (one cannot have a branch
  named `mob/main` and a branch named `mob/main/green` because
  `mob/main` cannot be a file and a directory at the same time).
