Doc shortcuts from libraries section don't honor "latest"

[joaquintides]

If I select "latest", go to

https://www.boost.org/libraries/latest/list/

and click on the circled book icon, I get

https://www.boost.org/doc/libs/boost_1_88_0/doc/html/accumulators.html

rather than

https://www.boost.org/doc/libs/latest/doc/html/accumulators.html
