🌟 Summary

Improvement to the Continuous Integration (CI) process by refining the broken link checker behavior.

📊 Key Changes

• 🛠 Updated the broken link checker GitHub Action to ignore additional HTTP statuses to reduce false positives.
• 🚫 Added status codes 403 (OpenVINO, 'forbidden'), 500 (Zenodo, 'cached'), and 502 (Zenodo, 'bad gateway') to the ignore list, in addition to pre-existing 429 (Instagram, 'too many requests') and 999 (LinkedIn, 'unknown status code').

🎯 Purpose & Impact

• 🎯 The purpose is to prevent the CI from failing due to false positives related to known service behaviors that aren't broken links.
• ✅ This will result in a more accurate and reliable CI process, ensuring that real issues are highlighted without being buried under falsely identified link issues.
• 🌐 For users, this change should mean a cleaner and more trustworthy report about the health of links in the project's documentation.
