docs: Revise the GS experience.

- Remove the information about timing.
  The LLM calls do not seem to be populated the same.

- Add reference to content safety notebook.

-  The timing and token information is available with the `print_llm_calls_summary()` method.
+- Run the `content_safety_tutorial.ipynb` notebook from the
+  [example notebooks](https://github.com/NVIDIA/NeMo-Guardrails/tree/develop/examples/notebooks)
+  directory of the GitHub repository.
+  The notebook compares LLM responses with and without safety checks and classifies responses
+  to sample prompts as _safe_ or _unsafe_.
+  The notebook shows how to measure the performance of the checks, focusing on how many unsafe
+  responses are blocked and how many safe responses are incorrectly blocked.
