[jameslamb]

The check-links CI job has been broken for a while. (most recent build link).

This PR fixes the 3 errors:

I'm able to navigate to https://www.tandfonline.com/doi/abs/10.1080/01621459.1958.10501479 in my browser without issue, and without being signed in to that website.

But curl -I (which issues a HEAD request), returns a 403 - Access Denied.

Looks like that site is behind CloudFlare, so the link checks are probably triggering some anti-DDoS protection 🤷🏻

This configuration change tells the check-links CI job to ignore that domain.

A similar issue with amd.com links was fixed by doing this same thing in the past here:

• [ci] broken link to AMD docs #3529
• [ci] fix check-docs error with AMD support website (fixes #3529) #3530
