fix(infra): pin virtio-container-disk to v1.8.2 (containerd 2.1 manifest fix)

KubeVirt v1.4.0 + RKE2 containerd 2.1.5 cannot pull
quay.io/kubevirt/virtio-container-disk:latest:
  rpc error: code = Unimplemented
  desc = failed to pull and unpack image: not implemented:
  media type "application/vnd.docker.distribution.manifest.v1+prettyjws"
  is no longer supported since containerd v2.1, please rebuild the image as
  "application/vnd.docker.distribution.manifest.v2+json" or
  "application/vnd.oci.image.manifest.v1+json"

The :latest tag was last rebuilt with the v1 manifest schema. Tagged versions
v1.6.5+, v1.7.3, v1.8.2 are rebuilt with v2/OCI manifests.

Pinning to v1.8.2 (newest available, contains current Windows VirtIO drivers).
The image only contains the Windows VirtIO driver ISO mounted as a CDROM —
not the KubeVirt runtime — so it is decoupled from the cluster KubeVirt
version.

-# =============================================================================
-# Windows Server 2025 ISO — Static NFS PV (Path B for SATA-CDROM timeout)
-# =============================================================================
-# Purpose: Mount the ISO from Synology NAS via NFS instead of from a Longhorn-
-# backed Filesystem PVC.
-#
-# Why: SATA-CDROM emulation reading from a Longhorn-backed Filesystem PVC is
-# too slow for OVMF's boot read window — the DVD-ROM enumeration times out
-# before the bootloader can be read. Symptom on the serial console:
-#   BdsDxe: failed to start Boot0001 "UEFI QEMU DVD-ROM QM00001 " from ...
-#   BdsDxe: failed to start Boot0001 ... Time out
-#   BdsDxe: No bootable option or device was found
-# Diagnosis confirmed the ISO content is a perfectly valid bootable ISO9660
-# image — the bug is in the timing path between OVMF and Longhorn-backed
-# storage, not in the ISO itself.
-#
-# Block-mode PVC was tried (`volumeMode: Block` via DataVolume) and would
-# likely fix the timing, but CDI v1.65.0's upload-target pod cannot open the
-# block device due to runAsUser:107 + capabilities.drop:[ALL] and we got:
-#   blockdev: cannot open /dev/cdi-block-volume: Permission denied
-#
-# NFS-mounted ISO bypasses both issues: no Longhorn slowness, no CDI upload
-# pod permission concerns. The ISO is read directly from the NAS over a
-# native NFSv4.1 mount that QEMU's SATA emulator can read at full LAN speed.
-#
-# Layout on Synology:
-#   /volume1/ISOs/                                              (existing export, RKE2 ACL)
-#     en-us_windows_server_2025_updated_march_2026_x64_dvd_8e06425a.iso
-#     win2025-iso-disk/                                         (new subdir, 2026-05-08)
-#       disk.img -> hardlink to ../en-us_windows_server_2025_..._8e06425a.iso
-#
-# KubeVirt's launcher pod expects a PVC mounted at
-# /var/run/kubevirt-private/vmi-disks/<diskName>/disk.img — by mounting the
-# `win2025-iso-disk/` subdir as the NFS PV root, `disk.img` lives at the PV's
-# root and KubeVirt's CDROM emulator finds it without any path manipulation.
-#
-# A symlink would NOT work for sub-path NFS mounts (the relative target
-# `../...iso` falls outside the sub-mount root). A hardlink works because it
-# references the same inode regardless of mount point.
-#
-# Memory references:
-#   - feedback_synology_nfs_volume1_kubernetes_export_scoped (Synology export
-#     scoping pattern — but /volume1/ISOs export, unlike /volume1/kubernetes,
-#     does support sub-path mounts because Synology NFS is configured with
-#     pseudo-fs in NFSv4.1)
-#   - feedback_kubevirt_iso_first_install_bootorder_and_runstrategy (boot
-#     order / runStrategy gotchas, separate from the storage timing issue)
-#
-# Validation (2026-05-08, from rke2-server / rke2-agent1 / rke2-agent2):
-#   mount -t nfs -o nfsvers=4.1,ro 10.0.58.3:/volume1/ISOs/win2025-iso-disk /tmp/m
-#   file /tmp/m/disk.img
-#     -> ISO 9660 CD-ROM filesystem data 'SSS_X64FRE_EN-US_DV9' (bootable)
-# All 3 RKE2 nodes can mount and read.
