version_tooltip doesn't seem to work as expected.

[olivroy]

I found one notable usage in the wild: the data.table package

https://github.com/Rdatatable/data.table/blob/master/_pkgdown.yml

However, the tooltip doesn't appear on their website. https://rdatatable.gitlab.io/data.table/

I couldn't find a way to make it work.

I tried to set it for tmap, https://github.com/r-tmap/tmap/commit/5568c3d156626e7308309269068f079affe218ef

but still shows the default in https://r-tmap.github.io/tmap/dev/
