The pr aims to update the link text and ref in notify_test_workflow.yml.

Why are the changes needed?

1.The keyword Disabling or limiting GitHub Actions for a repository does not exist on the page.

If a new user encounters the above issue, she/he will generally click on this page to search for Disabling or limiting GitHub Actions for a repository But unfortunately, the content of this page has changed and the keyword Disabling or limiting GitHub Actions for a repository no longer exists. I propose updating it to reduce user confusion.

Does this PR introduce any user-facing change?

Yes, only for dev.
