Subject: [PATCH] test(responses): bump deprecated gemini-3-pro-preview to
 gemini-3.1-pro-preview (#29433)

Google sunset gemini-3-pro-preview on the Gemini API, so the AI Studio
responses-API thought-signature tests started failing with a 404
("This model models/gemini-3-pro-preview is no longer available").
Point both tests at the current gemini-3.1-pro-preview model, which
litellm already has registered and which supports the function calling,
reasoning, and native streaming these tests exercise.
