Adding a param to the config while connecting to the session

Currently, the ElevenLabsRealtimeSTTService doesn't allow us to pass include_language_detection, which can be used to get the language code in the response of the Scribe ve realtime model. After discussing with the Elevenlabs team that this is the parameter name that can be passed to get the language code, I'm creating this PR

I'm happy to include this, but I can't find it in the reference docs. Can you point to where this parameter is listed in the reference docs? I'm not seeing it here:

Thanks for pointing out, I will flag this to their team.
The 11labs team suggested this parameter to get language_code in the response else this property will always come as None.

Below is the current response when we connect to Scribe v2 Realtime.
ElevenLabs session started: {'message_type': 'session_started', 'session_id': '15b88595fcc1dba279eefb', 'config': {'sample_rate': 8000, 'audio_format': 'pcm_8000', 'language_code': None, 'timestamps_granularity': 'word', 'vad_commit_strategy': False, 'vad_silence_threshold_secs': 1.5, 'vad_threshold': 0.4, 'min_speech_duration_ms': 100, 'min_silence_duration_ms': 100, 'max_tokens_to_recompute': 5, 'model_id': 'scribe_v2_realtime', 'disable_logging': False, 'include_timestamps': False, 'include_language_detection': False}}

Since this was launched 10 days ago, I'm sure they will be updating the docs soon to include include_language_detection and timestamps_granularity

@markbackman Met with the 11labs team, and the documentation is updated to have that param
