We improved the data quality and updated coverage for the following services

## Change We improved the data quality and updated coverage for the following services: * Improved mapping between Google Cloud services and internal resource use, particularly for a few Networking SKUs. * Removed App Engine (including Firestore and Datastore), Support, and Anthos from [covered services](https://cloud.google.com/carbon-footprint/docs/covered-services) of Carbon Footprint, due to potential mis-attribution of carbon to these services. We are actively investigating and working on the improvements. Once internal data consistency improves for a service, we plan to add it back. ## Change Updated carbon model to version 6
