Fix Grok Realtime voice type validation for server responses

Browse Source 
The Grok API now returns prefixed voice names (e.g. "human_Ara") in
session.updated events, causing Pydantic validation errors. Widen the
voice field type from GrokVoice to GrokVoice | str to accept both
user-facing names and server-returned values.
