Include 6.18 kernel bump and nested virt permissions

Install kernel 6.18.15-1~bpo13+1 (validated for ARM64 nested
virtualization on AmpereOne) and the matching NVIDIA driver
550.163.01-4~bpo13+1 from a snapshot.debian.org archive snapshot

Install kernel 6.18.15-1~bpo13+1 and the matching NVIDIA driver
550.163.01-4~bpo13+1 from a snapshot.debian.org archive snapshot,
matching the versions pinned by the preseed installer

The Debian cloud image enables trixie-backports by default, so
the pinned versions are installed unconditionally rather than
gated on backports detection

Append kvm-arm.mode=nested to GRUB command line so installed
hosts boot with KVM nested virtualization (NV2) enabled if
available
