Fix azure references for the latest openai apis

The open ai wrapper updated with latest apis for speech but the azure version did not reflect this update.

**Task**:
- Review the config links for azure openai services.
- Create sample azure app for testing.
- Update azure test cases.

**Impacted config**
- audiotranscriptions
- audiospeech

No files or test paths are named. Start by locating the Azure OpenAI configuration for audiotranscriptions and audiospeech, compare it with the updated speech wrapper, then review the existing Azure tests. Done means the config links are current, a sample Azure app exercises the services, and the Azure test cases pass.
