Refactor methods to use positional-only and keyword args

- Updated `create_api_endpoint`, `get_languages`, `get_task_status`, and
  `get_dubbed_run_info` to use positional-only parameters.
- Changed `get_all_voices` and other methods to use keyword-only
  parameters for optional arguments
- Ensured better clarity and parameter handling.
