The debian network installer needs these files too

Steps to reproduce:

    virt-install --osinfo debianbullseye --memory 1024 --disk size=10 \
      --location http://ftp.debian.org/debian/dists/bullseye/main/installer-amd64/current/images/netboot/debian-installer/amd64/,kernel=linux,initrd=initrd.gz \

The netboot installer will try to:

1. Read the Release file under binary-$arch
2. Download the Packages file under the debian-installer/binary-$arch
3. Download the microdebs which were described in such Package files
