Previously, in the "out of support", the link to the "latest" resource
was always targeting the home page of the latest version of the
component.
Now, the link targets the latest version of the current page when it
exists. The template use the "relativize" helper to make the url work
with local file browsing

Also update the `model-ui.yml` used for the preview to demonstrate the
change.
