fix(openrouter): fix crash of gpt-5.2-codex by using mode "chat" (#20577)

Browse source 
Commit 1cdda28b6 changed "openrouter/openai/gpt-5.2-codex" to mode "responses",
but this broke GPT-5.2-Codex with OpenRouter:

```
response = await litellm.acompletion(
            model="openrouter/openai/gpt-5.2-codex",
            messages=[{"role": "user", "content": "Hello"}],
            api_key=os.environ.get("OPENROUTER_API_KEY"),
)
```
crashes with: `OpenrouterException - argument of type 'NoneType' is not iterable`

Responses API is in beta in OpenRouter and no other OpenRouter models use "responses"
mode. The commit that changed this probably did it by mistake.

Therefore change the mode to "chat" and fix the crash.
