fix(compose): `network_mode` accept all podman values

[k9withabone]

Closes #38

• Support all podman run --network values for service network_mode
• Improve error message for unsupported values, link to the podman docs

The error message for network_mode values of service now looks like:

Error: 
   0: Could not parse service `test` as a valid podman command
   1: network_mode `service:` is not supported by podman

Location:
   src/cli/container/quadlet.rs:807

Suggestion: try using the `container:` network_mode instead
Suggestion: see the --network section of the podman-run(1) documentation for supported values: https://docs.podman.io/en/stable/markdown/podman-run.1.html#network-mode-net
