Summary

📝🛠️🔁

Improved the reliability and readability of the link checking workflow for the documentation. Used lychee instead of awesome_bot and added retries and comments in .github/workflows/links.yml.

To check links in the docs with lychee
We added a retry for more guarantee
And to make it more clear
We improved the comment here
So the workflow is easy to see

🌟 Summary

Improvements to Continuous Integration (CI) failure notifications and broken link checks in the Ultralytics GitHub workflow.

📊 Key Changes

• Modified CI failure notification conditions to trigger only for 'ultralytics/yolov5' repository and on schedule or push events.
• Updated the broken link checker to be more resilient by including retry logic and installing the latest lychee tool directly from GitHub releases.

🎯 Purpose & Impact

• Enhanced Precision for Notifications: Failure notifications will be more targeted, reducing noise for contributors and maintainers. 🛎️
• Increased Reliability of Link Checks: The adoption of a retry strategy ensures that transient network issues don't cause unnecessary failure alerts. 🔄
• Up-to-date Tooling: Using the latest version of lychee helps in accurate detection of broken links thanks to the latest features and fixes. 🆕

These changes can help maintain the quality of the repository by ensuring that contributors are only alerted for pertinent failures and that link integrity in documentation is reliably maintained.
