Preserve fixed retry delay in links workflow

[glenn-jocher]

Summary

Preserves the previous fixed 30-minute retry spacing in the links workflow after ultralytics/actions/retry switched to exponential backoff with jitter by default.

Changes

• add backoff: fixed to the retry-wrapped download step in .github/workflows/links.yml

Why

Without an explicit override, the second and third retries can expand beyond the intended 30-minute spacing.

🌟 Summary

🛠️ This PR updates the link-checking GitHub Actions workflow to use a fixed retry backoff, making documentation link checks more predictable and stable.

📊 Key Changes

• Added backoff: fixed to the .github/workflows/links.yml workflow.
• This change affects the retry behavior for the link-checking job when it encounters failures.
• The workflow still keeps the existing retry count and delay settings, but now retries happen with a consistent interval instead of a varying backoff pattern.

🎯 Purpose & Impact

• Improves reliability of automated link validation for the ultralytics/docs repository 🔗
• Makes retry timing more predictable, which can help when failures are caused by temporary external issues like slow websites or network hiccups ⏱️
• May reduce unexpected delays in CI runs and make troubleshooting easier for maintainers 🧪
• Helps keep documentation quality high by ensuring broken-link checks run more consistently 📚

🎉 Huge thanks for merging this, @glenn-jocher!

This is a small change with a meaningful impact—making link-check retries use a fixed backoff brings more predictability and stability to CI, which helps keep the Ultralytics docs workflow reliable and easier to troubleshoot. As Benjamin Franklin said, “An ounce of prevention is worth a pound of cure.” This update is a great example of that mindset in action: a thoughtful refinement that helps prevent flaky checks and supports consistently high documentation quality.

Really appreciate the care you put into these infrastructure improvements—they make a difference for everyone contributing to and relying on the docs. 🙌
