Adding an example local.json

[jeremy-seipelt]

In the Readme it says I need to set the Shopware 6 api credentials, but nowhere in the file is a shopware api credential shown.

I think I am supposed to add :

"shopware": {
      "imgUrl": "http://demo-shopware.io/pub/media/catalog/product",
     "assetPath": "assetPath",
     "api": { 
       "url": "link to shopware API",
       "consumerKey": "API ACCES KEY",
       "consumerSecret": "NOT Shown in SHOPWARE BACKEND",
       "accessToken": "NOT SHOWN IN SHOPWARE BACKEND,
       "accessTokenSecret": "NOT SHOWN IN SHOPWARE BACKEND"
     },
     "url": "SHOPURL"
}

I think the part needs further explaining, where the credentials need to be placed and what is required for a the credentials to be valid.

An example locale Json in the src code or inside the readme would help a lot
