condition_provider_uris is a dictionary in our Ursula Configuration; how is it updated via the CLI update command #3228
Description
Traditionally our config file contained key-value entries, where the values were basically strings/ints. However, with condition_provider_uris (v6/v7) this is a Dict[str, LIst[str] - how can that be updated via nucypher ursula config update ... for the command line? Do we handle dictionaries properly? How do you update the values for a specific key?
Follow-up issue fo #3227 .
