This method introduces a new body(Object) to ServerResponse, a shortcut to body(BodyInserters.fromObject(Object)). Note that in the implementation of the method, an `instanceof` check is performed to make sure that the passed argument is not a `Publisher`, as users should call `body(Publisher, Class)` for sending a reactive type. This Publisher-check is also done in the `WebClient`, for the same reasons. Issue: SPR-15461
