feat: Add RunPod start and improved pod creation

- Added a new `start_on_demand_pod` function to the RunPod client.
- Improved the `create_on_demand_pod` function to handle nested machine structure in the response.
- Updated the example to use the new functions and handle the new response structure.
- Updated the API key for the example.
- Added more descriptive field names in the `create_on_demand_pod` input.
