update asset manifest file name referenced in `WebServiceWorker` (#135954)

Closes https://github.com/flutter/flutter/issues/130455.

Updates the name `WebServiceWorker` uses to reference the asset manifest file to the name of the new file generated since   https://github.com/flutter/flutter/pull/131382. This will make Flutter web apps correctly prefetch the asset manifest file.
