Add podman and related packages to the base system install:

  podman
  podman-compose
  python-dotenv

These are required by winvm (~/code/winvm), which runs a Windows 11 VM
in a rootless Podman container via QEMU/KVM for Office, Visio, Adobe,
and other Windows-only applications. podman-compose manages the container
lifecycle and python-dotenv is a runtime dependency of podman-compose.
