[feature] Add support for the `path` key for configuration settings

[maks-oleksyuk]

The Readme file contains the following information:

The path to check can be overwritten with the --path option. If the path is one you always need checking you can place it in your peck.json file.

but I couldn't find any examples of how this could be configured and made to work

I expected the configuration to be similar to the following

{
    "preset": "laravel",
    "patch": [
      "app"  
    ]
}
