Great find and fix, @spiffytech! This is mergeable as soon as the DCO bot is happy.

Since the DCO does not apply to the chef-web-docs repo, and this is only a documentation update, I am going to accept this PR as-is. I will also be putting forth a Chef RFC/procedure change exempting in-repo docs-only changes (such as what we do in the chef/inspec repo) from DCO requirements.
