error when using a variable for PublishPort in systemd .container

[LangDuTienTu]

Feature request description

Atm if I use variable for PublishPort such as PublishPort=${PORT}:${PORT}, quadlet dryrun would show error message and quadlet cannot generate systemd service

invalid port format '${PORT}'

While we may use variable for Volume, why not PublishPort :3

Suggest potential solution

As the discussion: #24072

The reason it does not work for ports is that Quadlet does some validation checks: https://github.com/containers/podman/blob/main/pkg/systemd/quadlet/quadlet.go#L1957

Quadlet should only validate/parse the input when there's a strong reason, Quadlet could just pass on the value to --publish and let Podman take it from there

Have you considered any alternatives?
