distinguish host-containerd and containerd in diagram

**Path to page with conent (_do not_ include domain name):**

en/os/1.13.x/concepts/components/

**What content is incorrect?**

Not incorrect.

**What should the content say or communicate?**

Instead of having two items named `containerd` in the component diagram, maybe the one on the left should be named `host-containerd` (although maybe it wouldn't render well). Feel free to ignore this suggestion.

Open en/os/1.13.x/concepts/components/ and inspect the component diagram, focusing on the two items currently named containerd. Determine whether the left item can be renamed host-containerd without harming the diagram’s rendering, then verify the updated page displays the distinction clearly.
