Adjust patch for saa-non-cookie-storage

Spec now defines the `requestStorageAccess` parameter as optional, and notes
in an inline issue that this won't work unless Web IDL adopts a mechanism to
specify that a dictionary cannot be empty. In the meantime, the problem is the
same as before from a curation perspective.
