[bug] Missing span attributes in Guardrails Integration

[Jgilhuly]

Describe the bug
We're missing a few span attributes, specifically span_kind and inputs, within the guardrails integration. If you use llamaindex or langchain, those instrumentations fix the behavior, however if you just use OpenAI then the spans will be missing information.
