While testing a build, I noticed that the self-assment guide redirects weren't resolving from pages-for-subheaders/rancher-hardening-guides.md. I updated the links on that page to point to the current name for those pages. When I tested the links in docusaurus.config, it seemed like the redirects were formatted correctly and pointed to the right paths. I know we had a similar issue some months ago with other redirects. Updating the links on pages-for-subheaders/rancher-hardening-guides.md is a quick fix -- we still need to look into why the redirects weren't resolving.
