api: Add endpoint with list of language coverage for all languages
I'm planning to use the d-l api for l10n status info on apps.gnome.org.
However, with the current API I would have to call https://l10n.gnome.org/api/v1/modules/... for each language which is a lot of requests for static page generation (#apps * #languages).
Is there a chance that I could have a list of all translations with their status for a module? For example as REST href for each of the "branches"?
