aws cloudformation list-stack-resources --stack-name "mystack" 
{
    "StackResourceSummaries": [
        {
            "LogicalResourceId": "MyS3Bucket",
            "PhysicalResourceId": "mystack",
            "ResourceType": "AWS::S3::Bucket",
            "ResourceStatus": "CREATE_COMPLETE"
        }
    ]
}

**LastUpdatedTimestamp** is not returned.

## Expected behavior

Trying to use Localstack with some dependencies which expects the field LastUpdatedTimestamp. I saw in few older posts the field was being returned.
