docs: You can use settings to get additional information from the user via their
      dependencies.io configuration file. Settings will be automatically injected as
      env variables with the "SETTING_" prefix.
  
      All settings will be passed as strings. More complex types will be json
      encoded. You should always provide defaults, if possible.
