Translated HTML publications with whitehall-frontend as rendering app

[fofr]

There's about 308 HTML publications with their rendering app set to whitehall-frontend rather than government-frontend. Each of these URLs ends with a number, suggesting they are all translations.

Translation URLs change when the content is updated. This suggests that perhaps the old content isn't being cleaned up correctly and that the old URLs are not being redirected to the new ones.
