Python: Remove a stale Args block from a samples docstring - #10233

Motivation & Context

run_chat_client() in python/samples/02-agents/observability/advanced_manual_setup_console_output.py takes no parameters:

async def run_chat_client() -> None:

but its docstring documents one:

    Args:
        stream: Whether to use streaming for the plugin

Nothing in the function reads stream, and "for the plugin" points at where the paragraph came from — a sibling plugin sample. Someone reading this file to learn how streaming is enabled will look for the parameter, not find it, and have to decide whether the sample is stale or they opened the wrong overload.

Description & Review Guide

• What are the major changes? Three lines removed from one docstring: the Args: heading, the stream: entry, and the blank line that separated it from Remarks:.
• What is the impact of these changes? None at runtime. The rest of the docstring — the summary, the telemetry paragraphs, and the Remarks: block — is untouched.
• What do you want reviewers to focus on? Whether removing the block is the right call versus adding the parameter. I read the function body and found no stream usage and no streaming branch, so documenting it seemed like the smaller fix than inventing behaviour; if the intent was that this sample should demonstrate streaming, the parameter is the thing to add and I can do that instead.

Assisted areas: documentation. A scan of this repository's docstrings compared each Args: entry against the actual signature and reported this function as the single mismatch in python/ (1342 files). I read the function to confirm it takes no arguments and does not reference stream, and re-ran the same scan after the edit to confirm the mismatch count went from 1 to 0.
