`podman-compose ls` command is missing

[ccll]

Is your feature request related to a problem? Please describe.

docker-compose ls can list the running compose project in the system and their path, which is convenient to find out all the projects.

podman-compose seems don't have this command implemented.

$ podman-compose ls
...
podman-compose: error: argument command: invalid choice: 'ls' (choose from 'help', 'version', 'wait', 'systemd', 'pull', 'push', 'build', 'up', 'down', 'ps', 'run', 'exec', 'start', 'stop', 'restart', 'logs', 'config', 'port', 'pause', 'unpause', 'kill', 'stats', 'images')

I run many server machines and each of them run some different compose projects from different path, I hardly remember any of them, so every time I log into one machine, I just use docker-compose ls to get a overview of all the projects and where are they.

Describe the solution you'd like
Let podman-compose ls do the same thing.

Describe alternatives you've considered

This issue also affects deployment of OpenEdx 20.0.1 using tutor when podman and podman-compose is installed instead of docker and docker-compose.

tutor uses a call to docker-compose with ls --format json which is not supported by podman and podman-compose:

docker compose -f /opt/openedx/tutor/env/local/docker-compose.yml -f /opt/openedx/tutor/env/dev/docker-compose.yml --project-name tutor_dev ls --format json

from the error log:

docker compose -f /opt/openedx/tutor/env/local/docker-compose.yml -f /opt/openedx/tutor/env/dev/docker-compose.yml --project-name tutor_dev ls --format json

podman and podman-compose versions:

$ podman-compose version
podman-compose version 1.5.0
podman version 5.4.0`

Sample output of docker compose (from another server where docker and docker-compose is installed):

$ docker compose ls
NAME                STATUS              CONFIG FILES
tutor_local         running(11)         /home/openedx/.local/share/tutor/env/local/docker-compose.yml,/home/openedx/.local/share/tutor/env/local/docker-compose.prod.yml

$ docker compose ls --format json
[{"Name":"tutor_local","Status":"running(11)","ConfigFiles":"/home/openedx/.local/share/tutor/env/local/docker-compose.yml,/home/openedx/.local/share/tutor/env/local/docker-compose.prod.yml"}]

As you can see, this parameter will list containers currently running, and this is required by tutor
