Subject: [PATCH] docs: update default Inworld TTS model to inworld-tts-2

Updates documentation to reflect the change in PR #4422 where the default
TTS model was changed from inworld-tts-1.5-max to inworld-tts-2 across
InworldRealtimeLLMService, InworldTTSService, and InworldHttpTTSService.

Changes:
- Updated default value in Configuration sections
- Updated code examples to use new default model
- Both old models (inworld-tts-1.5-max and inworld-tts-1.5-mini) remain valid
