This PR adds a Respan observability integration page to LiteLLM's docs.

Respan (formerly Keywords AI) is an LLM engineering platform for observability, evaluation, and gateway routing. The integration uses LiteLLM's existing built-in OpenTelemetry callback (`callbacks=["otel"]`) plus standard `OTEL_EXPORTER_OTLP_*` environment variables — no new Python package or LiteLLM code change is required.

Changes

  • Add `docs/observability/respan_integration.md` — dedicated provider page modeled after `langfuse_otel_integration.md`. Covers:
    • SDK setup (basic + metadata example)
    • LiteLLM Proxy setup (env vars + `config.yaml`)
    • Data collected
    • Troubleshooting (auth + verbose logging)
  • Add a "Log to Respan" tab to `docs/observability/opentelemetry_integration.md` alongside the other generic-OTel destinations (Traceloop, Laminar, Splunk) for discoverability

Notes for reviewers

Happy to make any adjustments — naming, file location, tone, or to drop the tab addition if you'd prefer the dedicated page only.

Adds documentation for sending LiteLLM traces to Respan
(formerly Keywords AI) using LiteLLM's built-in OpenTelemetry
callback and the standard OTEL_EXPORTER_OTLP_* environment
variables. No Respan-specific Python package is required.

- Add docs/observability/respan_integration.md (dedicated page,
  modeled after langfuse_otel_integration.md): SDK and Proxy
  setup, environment variables, metadata example, troubleshooting
- Add a "Log to Respan" tab to docs/observability/opentelemetry_integration.md
  alongside the other generic-OTel destinations (Traceloop, Laminar,
  Splunk) for discoverability

The sidebar entry is auto-generated from the observability
directory, so no sidebars.js change is needed.
