(cli): "ls" command alias prints an error message to the terminal

[nomike]

Describe the bug

When running cdk ls, I'm getting the following output on stderr:

$ cdk ls >/dev/null
Unknown option(s): --long, --l, --show-dependencies, --d, --showDependencies. These will be ignored. Run 'cdk --help' to see available options.

The cdk --help clearly documents this as a valid alias:

$ cdk --help
Usage: cdk -a <cdk-app> COMMAND

Commands:
  cdk list [STACKS..]             Lists all stacks in the app      [aliases: ls]
...

After that, cdk seems to go on normally.
