Artifact Registry now calculates fingerprints for each version of a package

You can use the fingerprint to validate that the package wasn't modified when moving between Google Cloud systems, such as Compute Engine and Cloud Build. This feature is in[public preview](https://cloud.google.com/products/#product-launch-stages).
