without this change we set only a single extension "response-transformer" without an option to provide any other ones
with this change we introduce the "spring.factories" based extension model. It's enough to provide your own implementation of `org.springframework.cloud.contract.verifier.dsl.wiremock.WireMockExtensions` and register it in `spring.factories`. That way you can control all extensions (request / response).
