Previous behavior:
Sometimes Google Cloud authentication fails, this might happen before
IAM permissions are fully propagated
Expected behavior:
If the authentication fails, retry at least 3 times before exiting with
a non zero exit code
Applied solution:
Google GitHub Actions for auth recently added this a `retries` feature
which is now implemented to workaround this issue.
