[IMP] script todo: add "principal" choice to infra (one main VM per distro)

The infra distribution prompt now accepts "principal" (alongside
numbers and "all"): it deploys the default version of each distro —
ubuntu 24.04, debian 12, fedora 42 — one VM each. The default version is
also marked with a * in the distro listing so it is visible.
