Resolves the documentation gap raised in cakephp/cakephp#19511.
withStringBody()sets the response body but, by itself, has no visible effect when an action neither returns the response nor disables view rendering. In that caseController::invokeAction()still callsrender()and overwrites the body. This was undocumented and unintuitive.Adds a warning note to the "Setting the Body" section explaining the two ways to make the string body take effect: return the response, or
setResponse()plusdisableAutoRender().
