Sync service maturity manifest

This MR is automatically generated by Scalability team, as a part of maturity model automation project.

The service maturity model page shows the output of our service maturity model for each service in our metrics catalog. The model itself is part of the metrics catalog, and uses information from the metrics catalog and the service catalog to score each service. The purpose of this MR is to re-compute and sync the manifest from the runbook.
