Unconditional mapping to 'app.json' for Expo SDK hurts Heroku users

{
      "name": "Expo SDK",
      "description": "JSON schema for Expo SDK app manifest",
      "fileMatch": [
         "app.json"
      ],
      "url": "https://json.schemastore.org/expo-37.0.0.json"
    }

Just as I try to stay away from Expo in React world, they are finding new ways to inject themselves into my workflow.

Webstorm somehow thinks every app.json in a React project should conform to "json.schemastore.org/expo-37.0.0.json"

As a workaround, while this problem ages like fine wine, I've taken to specifying the $schema directly in my app.json files using the raw schema from the PR for IDEA-244881 thusly:

{
  "$schema": "https://raw.githubusercontent.com/crcastle/schemastore/06174ef73fcaa1f9734e4aed8b7d40e6df586f76/src/schemas/json/app.json",
  ...
}

@mogsdad Good find! In the preferences menu, you can take that URL and stick it inside the JSON Schema Mappings, and that solves the problem in an elegant way.

Just remember that this way only solves the problem for one developer!

It works for all developers using a JetBrains IDE if you commit .idea/jsonSchemas.xml.
