Update GitHub Actions workflow to improve analysis output formatting

- Modified the analyze job to append results to the output file instead of overwriting it, preserving previous analysis data.
- Added markdown formatting to the results file for better readability, including a header and code block encapsulation.
- Included a timestamp and Python version information at the end of the results file for context.
