Gemini deprecates temperature, top_p and top_k

Google deprecated the temperature, top_p and top_k sampling parameters. The Gemini 3.6 Flash guide says the API ignores them now and will return an HTTP 400 error for them in future model generations.

Who is affected:

Apps that set temperature, top_p or top_k on Gemini requests.

Action needed:

Remove temperature, top_p and top_k from Gemini requests.
