By using a `with` block, we make sure that the file-like object is closed after the generator function (the function with `yield`) is done. So, after it finishes sending the response.

It wouldn't be that important in this specific example because it's a fake in-memory file (with `io.BytesIO`), but with a real file, it would be important to make sure the file is closed after the work with it is done.
