scenario `-- --help` is broken by new internal client structure

The issue is that when we pass -- -- help to learn a scenario's options we actually run the scenario file locally. The problem with that is now we assume scenarios are only run inside the cluster, with access to the kubernetes internal client:

(.venv) --> warnet run scenarios/miner_std.py -- --help
