Feature/Add Azure Cognitive speech-to-text functionality (#3718)

* feat: Add Azure Cognitive Services integration for speech-to-text functionality

- Introduced a new credential class for Azure Cognitive Services.
- Updated speech-to-text processing to support Azure Cognitive Services as a provider.
- Enhanced UI components to include Azure Cognitive Services options and inputs for configuration.
- Added necessary imports and error handling for Azure API requests.

* Update SpeechToText.jsx linting

* refactor: Update audio file handling in SpeechToText component

- Removed the dependency on 'form-data' and replaced it with a Blob for audio file uploads.
- Simplified the audio file appending process to the form data.
- Cleaned up the headers in the Axios request by removing unnecessary form data headers.

This change enhances the efficiency of audio file processing in the speech-to-text functionality.
