Update React Autocomplete with results example

Please update:

with updated example from the site:

Also, how do you prevent the Autocomplete query value from being passed to the VirtualSearchBox until the user either clicks enter or picks an autocomplete suggestion? It would be nice if one of these widgets could use a SearchAsYouType property.

Thanks.

Start by comparing the React InstantSearch autocomplete-results-page sample with the linked Algolia autocomplete guide. Update the sample to match the guide, then investigate how the Autocomplete query interacts with VirtualSearchBox and whether the requested SearchAsYouType behavior is supported; done means the example is current and that behavior is clarified.
