Update example templates to modern distros

Replace CoreOS (EOL) with Flatcar Linux using Ignition v3.
Replace CentOS (EOL) with AlmaLinux using a kickstart template.
Update Ubuntu templates to jammy with current archive mirror paths.
Update Debian template to bookworm.
Drop CoreOS cloud-config; add Flatcar Ignition example.
Update mappings.yaml, test configs, fixtures, and smoke test accordingly.
