Setting up custom package indexes

To set up a custom package index, complete the following steps:

1. Open the config.json configuration file located at ~/.nrfutil/config/nrfutil-core/.
2. Add a new entry under the package_indexes section:

   {
     "package_indexes": {
       "custom-internal": {
         "url": "https://your-internal-server.example.com/packages/index.json"
       }
     }
   }
   

3. Ensure the url points to a valid package index JSON file.
4. Reference this package index name in your modifiers configuration or when using nRF Util commands.
