Update openai spans to be OTel compatible

[antonpirker]

Change the spans name, op, and attributes to the new OTel compatible names.

We checked and none of our customers use those legacy span names, span ops, or attribute names in alerts, dashboards, or saved queries so this is save to change in a minor.
