@sima-zhu can you please help me understand where this broken link issue is coming from as part of the Link verification check and why it is getting flagged in this PR when it isn't modifying that markdown at all (and not in previous CI runs)?

cc: @ewertons the link failure you had is showing up in master. What was the fix you applied in your PR?

Alright, syncing with master resolved the issue. My branch was just out-of-sync, and there is no link verification issue.
