  # Build and push the cloud-api-adaptor image
  #
  # By using a reusable `workflow_call` workflow we are hitting two
  # GHA limitations here:
  #
  # - Cannot access the `env` context from the `with` so that it cannot
  #   reuse the E2E_IMG_* environment variables set at this workflow level.
  # - Cannot call a reusable workflow from a job's step, so the we cannot
  #   merge the `image` and `prep_env` into a single one (unless we create
  #   another reusable workflow and, well, likely hit another limitation...).
