fix(core): Fix operation name for openai responses API (#17206)

According to
https://opentelemetry.io/docs/specs/semconv/registry/attributes/gen-ai/#gen-ai-operation-name

> “If one of them applies, then the respective value MUST be used;
otherwise, a custom value MAY be used.”

and because the responses api also allows file and image input we can
assume it's not really a chat completion

closes: #17192
