Correct Cloud Run DomainMapping namespace in encoder

[rileykarson]

Fixes hashicorp/terraform-provider-google#4651

The correct namespace (apiVersion) for DomainMapping is domains.cloudrun.com/v1alpha1. Previously, the value was ignored but now it's being validated.

          {
            "field": "api_version",
            "description": "Unsupported API version 'serving.knative.dev/v1alpha1'"
          }
        ]
