Cherry pick '846-basic-installation-of-nokogiri' into '13.4'

We need to backport !1111 (merged) to 13.4, as its pipeline will fail otherwise. Reason:

!1111 (merged) removed the system libraries needed by Nokogiri and used the ones that come with the gem instead. The Docker images have been updated, but .gitlab-ci.yml of the old branches still use NOKOGIRI_USE_SYSTEM_LIBRARIES=1 when installing the gems.
