debian-installer can be preseeded with `base-installer/install-recommends` to
disable installation of recommended packages already during OS installation.
d-i will then create the file `/etc/apt/apt.conf.d/00InstallRecommends`
(cf. https://salsa.debian.org/installer-team/base-installer/-/blob/master/library.sh).
__apt_norecommends should use the same file to avoid having two config files
effectively doing the same thing.
