Send a Bodyless REST Request into a StringBuilder

Demonstrates Rest.FullRequestNoBodySb, which sends a request with no body and stores the text response body in a StringBuilder.

Background. This variant of the no-body full request writes the response into a StringBuilder rather than returning it as a string, which is convenient when the response will be further processed in place.
