Added note about gpt-5 model config, as it doesn't support obsolete parameters like "temperature" and "top_p", which are still available in the Agents Playground. That's why the value of those 2 parameters should remain at default "1" to prevent "unsupported parameter" error message.

Pull Request Overview

This PR adds a proactive note about gpt-5 model configuration in the Agents Playground to prevent common user errors. Since gpt-5 models do not support the obsolete temperature and top_p parameters that are still present in the UI, users need guidance to avoid encountering "unsupported parameter" errors.

Key changes:

  • Added documentation note warning users to keep temperature and top_p at default value of 1 when using gpt-5 models in Agents Playground

> * Brazil south
> * The gpt-5 models are available for the [code interpreter](../how-to/tools/code-interpreter.md) and [file search](../how-to/tools/file-search.md) tools
> * [Registration](https://aka.ms/openai/gpt-5/2025-08-07) is required to use the gpt-5 models. Access will be granted according to Microsoft's eligibility criteria.
> * As gpt-5 models [don't support](../../openai/how-to/reasoning.md?tabs=gpt-5%2Cpython%2Cpy#not-supported) `temperature` and `top_p` parameters, leave their values set to `1` in the Agents Playground, to avoid "unsupported parameter" errors.

[nitpick] The phrasing 'leave their values set to 1' is ambiguous about whether this is the default state or requires user action. Consider rephrasing to: 'keep the default values of 1 for both parameters' or 'don't modify the default temperature and top_p values (both set to 1)' to clarify that maintaining defaults is the solution.

Use 'because' instead of 'as' to start the sentence. Following the Microsoft Writing Style Guide, 'because' is clearer and more direct than 'as' when expressing causation. The sentence should begin: 'Because gpt-5 models don't support...'
