🌟 Summary

Enhanced GitHub Actions configuration for improved link checking in the documentation.

📊 Key Changes

• Updated the broken link checker to ignore additional HTTP status codes (403, 500, 502) that lead to false positives.
• Condensed redundant link check commands within GitHub Actions into more efficient configurations.
• Ensured that a wider range of file types (Markdown, HTML, YAML, Python, and Jupyter Notebooks) are included in link checking on manual trigger (workflow_dispatch).

🎯 Purpose & Impact

• Minimizing False Alarms: By ignoring certain error codes like 403 (Forbidden), 500 (Internal Server Error), and 502 (Bad Gateway), the CI process reduces noise from transient network or server issues that are not actual broken links.
• Streamlining CI Processes: The update leads to a cleaner and more maintainable GitHub Actions workflow, saving processing time and resources.
• Comprehensive Link Verification: Expanding file type coverage ensures that links in documentation and code notebooks are also verified, leading to higher overall documentation quality.

This update improves the reliability and efficiency of documentation quality checks, allowing developers and users to trust the links and resources provided in Ultralytics documentation.
