feat(python): speech-to-text v2 — streaming-multilingual

[github-actions]

Adds the streaming-multilingual recipe for speech-to-text v2 (Python).

Demonstrates Deepgram's Flux Multilingual model (flux-general-multi) via the v2 WebSocket API with per-turn language detection. The example streams audio and displays detected languages alongside the transcript for each conversational turn.

Key features shown:

• flux-general-multi model for 10-language support
• Per-turn languages field on TurnInfo events
• Language hint configuration via request_options
• Mid-stream language hint reconfiguration via Configure control message (documented in README)

Closes #521
