Enhance JSON handling and debugging in GitHub Actions

- Updated get_module_path.js to ensure proper JSON formatting and added logging for the final output.
- Modified lint.yml to parse and log the module names output correctly, improving visibility into the workflow's execution.

These changes improve error handling and debugging capabilities in the CI workflow.
