🚀 Feature: Emit OTel Log Events following GenAI semconv for LangChain

[aabmass]

Which component is this feature for?

Langchain Instrumentation

🔖 Feature description

Hello 👋 The latest OTel Gen AI semantic conventions put prompt content into OTel Log Events instead of Span attributes/events. In particular, it would be great to see this for LangChain/LangGraph instrumentations.

🎤 Why is this feature needed ?

So telemetry matches the current OTel semantic conventions

✌️ How do you aim to achieve this?

I haven't been joining the GenAI Semconv WG meetings and don't know the current plan. If the plan is to move instrumentation into OTel, I can work on that and implement it in OTel repos.

Otherwise, I can send PRs here.
