Add Support for `gen_ai` semantic-convention breaking changes in v1.37.0

Is your feature request related to a problem?

The gen_ai fields are not using the latest semantic convention. It looks like this was supposed to be done in this PR https://github.com/open-telemetry/opentelemetry-python/pull/4731/changes#diff-25ace29f4af9b016a152aad40987138b245a5dcee698581ecdcb3fb106455b58 but using the latest sdk version v1.39.1, it appears the gen_ai fields are still using the only semantic convention (labels.gen_ai_prompt).

Describe the solution you'd like

In the v1.37.0 release https://github.com/open-telemetry/semantic-conventions/releases/tag/v1.37.0, it added breaking changers for gen_ai fields. Can we double check that the fields are properly ingested and follow the latest convention.

Start by comparing the current gen_ai fields, including labels.gen_ai_prompt, with the OpenTelemetry semantic-conventions v1.37.0 release. Review PR 4731 and verify the behavior against SDK version v1.39.1. Done means the fields are properly ingested and follow the latest gen_ai convention.
