Implement CSV output redirection and enhance result printing in GitHub Stats Analyzer

- Introduced StringIO for capturing CSV output, allowing for cleaner result handling.
- Updated main execution flow to redirect output to a temporary file for CSV and JSON formats, preventing log message mixing.
- Added a new test script to validate CSV output format, ensuring expected results are produced.
- Modified existing tests to reflect changes in output formatting and improve consistency in test assertions.
