Issue 17927 (https://github.com/kubernetes/website/issues/17927) asks for a change to this task-focused doc on security-context. It notes that this doesn't mention read-only root filesystem, while it's documented in the PSP page. This adds a bullet for read-only rootfs, clarifies that the bulleted list isn't comprehensive, and tells someone reading the list where to find more. The link is copied from the existing What's Next link list.
