Crash when passing -v to container command

[akloeker]

Minimal example:

Command:

docker-run ubuntu:22.04 echo -v

Output:

Traceback (most recent call last):
  File "/usr/lib/python3.10/runpy.py", line 196, in _run_module_as_main
    return _run_code(code, main_globals, None,
  File "/usr/lib/python3.10/runpy.py", line 86, in _run_code
    exec(code, run_globals)
  File "/home/sysadmin/.local/lib/python3.10/site-packages/docker_run/__main__.py", line 5, in <module>
    generateDockerCommand()
  File "/home/sysadmin/.local/lib/python3.10/site-packages/docker_run/core.py", line 178, in generateDockerCommand
    cmd = buildDockerCommand(vars(args), unknown_args, cmd_args)
  File "/home/sysadmin/.local/lib/python3.10/site-packages/docker_run/core.py", line 151, in buildDockerCommand
    docker_cmd = plugin.modifyFinalCommand(docker_cmd, args, unknown_args)
  File "/home/sysadmin/.local/lib/python3.10/site-packages/docker_run/plugins/core.py", line 63, in modifyFinalCommand
    cmd = cls.resolveRelativeVolumeFlags(cmd)
  File "/home/sysadmin/.local/lib/python3.10/site-packages/docker_run/plugins/core.py", line 142, in resolveRelativeVolumeFlags
    mount_path = cmd[i + 1].split(":")[0]
IndexError: list index out of range

Expected Output:

-v

For comparison, normal docker run works fine.

Command:

docker run ubuntu:22.04 echo -v

Output:

-v
