docs: // ContainerWait waits until the given container is in a certain state
  // indicated by the given condition. If the container is not found, a nil
  // channel and non-nil error is returned immediately. If the container is
  // found, a status result will be sent on the returned channel once the wait
  // condition is met or if an error occurs waiting for the container (such as a
  // context timeout or cancellation). On a successful wait, the exit code of the
  // container is returned in the status with a non-nil Err() value.
