feat(apt): Add non-free-firmware component to all repos

We're doing this because at the end of the Proxmox VE 8 lifecycle in
August of 2025 the pve8to9 migration check script indicated if would
be potentially beneficial to install the amd64-microcode package for
microcode updates to our processor.

We agree which is why we need the non-free-firmware component to be
able to install amd64-microcode.
