Fix unminimize to correctly list packages (LP: #1996489)

    Prior to dpkg/1.21.0, there was a bug where dpkg -V/--verify
    couldn't list all the correct packages correctly but with
    that being fix and in archive since Jammy, this works perfectly
    but the syntax to report the missing files have changed. It
    just prints 'missing' now. With that new format, we can now
    fix the regex to simply list the packages.

    With this patch, the unminimize script works flawlessly
    on a minimized image.

    (cherry picked from commit 78a98c6835)

    fix: install LXD snap from stable/ubuntu-<version> channel (LP: #2036725)

    In the past, we'd directly snap install lxd which defaults to
    the latest/stable channel. However, whilst working on enhancing
    unminimize, it was observed that we install this snap from
    the stable/ubuntu-<version> channel instead.

    This was also noted as a failure when running the CTF tests:
    `lxd installed from latest/stable, not stable/ubuntu-23.10`

    (cherry picked from commit 12a2109c22)
