fix(remix): Clone erroneous responses not to consume their body strea…

…ms. (#5429)

Fixes: #5423

Ref: #5405 

We were extracting the bodies of 4xx/5xx responses to capture, but Remix also uses them, we should not consume their `body` streams, as they are only available once in response lifespans. 

This PR updates `extractData` to work on a clone response.
