Feature Request: Add request/response headers to response state

[filipebarcos]

This is just a feature request. When we submit the VGS form, it's often forwarding/proxying the request to elsewhere. These requests often come with useful headers, like idempotency keys or request IDs that could be useful to have handy for investigations when things go wrong (specially).

const [response] = useVGSCollectResponse();

useEffect(() => {
  console.dir({ 
    headers: { 
      response: response.headers, 
      request: response.requestHeaders,
    }, 
  });
}, [response]);
