Effect spans fall back to op function when we don't detect spans that should be op http.server or http.client. I'm going to assume this is intended and moreover, assume that these spans are actual function spans. This is good because it means they're already low cardinality and adhere to the conventions span name spec. So the only thing left to do was setting the code.function.name attribute for span description inference.

ref #23954

Ok so i think we should just remove the fallback op for function instead. we don't know at all what calls this helper so I'd rather not pretend these are sentry-created spans.
