chore: add debugging steps for PraisonAI API key validation in GitHub Actions workflow

- Introduced additional checks to verify the presence and validity of the OpenAI API key within the workflow.
- Added a new step to directly test the PraisonAI API key usage, enhancing visibility into the API key configuration and its integration with the PraisonAI model.
- These changes aim to improve debugging capabilities and ensure proper API key handling during the workflow execution.
