[Feature] openbb-platform-api: Adds Configurations Supplied In Router Decorator To widgets.json

[deeleeramone]

1. Why?:

   • Provides a way to define some, or all, widget configuration settings that will override the automatically-generated content.

2. What?:

   • Reads a dictionary supplied in the @router.command decorator and updates the generated widget entry with the supplied settings.

3. Impact:

   • Improves developer experience.
   • Requires knowing the nested dictionary structure that is widgets.json.

4. Testing Done:

   • Some router extension, and change the "type".

"""Empty Router Extenision for OpenBB Platform."""
