Bug#1036950: schleuder: fails to upgrade from 'buster': fails during apt-get upgrade

[Andreas Beckmann]

Followup-For: Bug #1036950

after the changes in 3.6.0-3+deb11u1 schleuder seems to be no longer
compatible with ruby-activerecord/buster and therefore seems to need
a versioned Depends: ruby-activerecord (>> 2:6)
