--dry-run misses podman version output…

[rugk]

STR

Any simple compose fle.
Command: podman-compose --dry-run -p caddy up

For an example, see #316

What happens

What I discovered:

• It does not show the podman version as the first line/startup.
• It misses the image generation, i.e. sth. like podman volume inspect caddy_caddy_data || podman volume create caddy_caddy_data
  Edit: Oh, I overlooked that, it does, actually show this.

What should happen

The things above should also be included in the dry-run.

System

$ podman-compose version
using podman version: podman version 3.2.0
podman-composer version  0.1.7dev
podman --version
podman version 3.2.0
0
$ podman version
Version:      3.2.0
API Version:  3.2.0
Go Version:   go1.16.3
Built:        Wed Jun  9 16:24:16 2021
OS/Arch:      linux/amd64

same as in #314, basically

What it also misses is of course the reply of the hashes of the containers etc. created by podman, but I guess this is okay/to be expected. 🙃

I guess I've just fixed that.
