   Checks whether you have the required permissions for the action,
   without actually making the request, and provides an error response.
   If you have the required permissions, the error response is
   `DryRunOperation`. Otherwise, it is `UnauthorizedOperation`.
 @option options [required, String] :instance_id
   The ID of the instance to unlink from the VPC.
