Fix permalink for newest version of template

Copying the permalink using the "get permalink" button and pasting it in a new window produces the following error: "404 page not found"

This only happens for the current version, the older versions work fine

Reproduce the issue with the “get permalink” button for the current template version, then inspect the permalink-generation and routing entry points in the Go website. Compare the generated current-version URL with one for an older version; done means the current permalink opens successfully instead of returning 404.
