RDocumentation used to make badges available as
https://www.rdocumentation.org/badges/version/<PKG_NAME>
but they seem to be unavailable since a couple of weeks at least...
This is impacting many projects, see https://github.com/search?q=rdocumentation.org%2Fbadges%2Fversion&type=code
It would be nice to know if such badges are just temporarily not working or they are not going to be provided any longer.
