Summary

🛠️🚫🔗

This pull request improves the link checker workflow by allowing manual triggers, reducing false positives, and excluding irrelevant domains and files.

To avoid false alarms and frustration
We updated the link checker workflow
Now it runs on demand with some exclusion
Of domains and files that we know
Are valid and don't need to be checked so

Walkthrough

• Remove workflow triggers on push and pull request events to master branch, and enable manual trigger by workflow_dispatch event (link)
• Adjust link checker command to accept only 429 and 999 status codes, and exclude links from twitter.com, instagram.com and url.com (link, link)
• Simplify exclude-path argument for link checker command by using glob pattern instead of listing each file (link)

🌟 Summary

Improved link-checking workflow in GitHub repository.

📊 Key Changes

• Removed link-checking on each push and pull request to master branch.
• Updated the lychee link checker command options:
  • Changed accepted HTTP statuses to only include 429 and 999.
  • Expanded the exclusion list to include Instagram links in addition to Twitter.

🎯 Purpose & Impact

• Reduces unnecessary workflow runs: Not running link checks on every push or pull request can save CI resources and reduce notification noise.
• Streamlined link-checking: By limiting accepted statuses, the check focuses on more critical link issues, enhancing the relevance of the workflow.
• Prevents false positives: Excluding certain domains like Instagram ensures that the link checker doesn't fail due to specific site restrictions or behaviors, leading to more accurate CI outcomes for documentation quality.

The changes should make the repository maintenance more efficient and the link-check status more actionable for maintainers and contributors. 🚀
