Add tests for audio input (#1946)

<!-- ELLIPSIS_HIDDEN -->



> [!IMPORTANT]
> Adds `AudioInputOpenai` function for handling audio input with a
prompt, including tests and multi-language support.
> 
>   - **Behavior**:
> - Adds `AudioInputOpenai` function to handle audio input with a prompt
in `openai_client.rs`, `client.go`, and `async_client.py`.
>     - Supports both synchronous and asynchronous operations.
>   - **Tests**:
>     - Adds tests for `AudioInputOpenai` in `test_functions.py`.
>   - **Misc**:
>     - Updates `openapi.yaml` to include `AudioInputOpenai` endpoint.
> - Adds `AudioInputOpenai` to various client files across different
languages (e.g., TypeScript, Ruby).
