docker warnings break parsing of docker output.

[rukai]

warnings generated by docker-compose.yaml issues will cause failures to parse docker output.
For example, consider this snippet from the crate:

        let containers = run_command(
            "docker",
            &["compose", "-f", file_path, "ps", "--status", status],
        )
        .unwrap();
        // One line for the table heading. If there are more lines then there is some data indicating that containers exist with this status
        if containers.matches('\n').count() > 1 {
            panic!(
                "At least one container failed to initialize\n{containers}\nFull log\n{full_log}"
            );
        }

If a warning is emitted an extra line will be included causing the if statement to run when it should not run.

We need to fix this case to handle warnings AND check for other cases where we might be parsing output and need to ignore warnings.

An example method for reproducing the issue is adding the version: '3' field to the top of the yaml, this will trigger a deprecation warning.
