    # notably, this is essentially the same script as `new-release-branch.yaml` (with fewer inputs), but it assumes the branch already exists
    # do note that executing the transform below will prevent the `configurePrerelease` script from running on the source, as it makes the
    # `version` identifier no longer match the regex it uses
    # required client_payload members:
    # branch_name - the target branch
    # package_version - the full version string (eg, `3.9.1-rc` or `3.9.2`)
    # core_major_minor - the major.minor pair associated with the desired package_version (eg, `3.9` for `3.9.3`)
