fix(iso): use Ubuntu jammy codename for AMD ROCm repo — Debian not supported
AMD does not publish Debian Bookworm packages at all (only focal/jammy/noble). Switch ROCM_UBUNTU_DIST to "jammy"; jammy packages install cleanly on Debian 12 due to compatible glibc. Also expand candidate list to include point-releases (6.3.4, 6.3.3, …) so we pick the latest actually-published one. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
