 *     - Resolve the config plugin as-is
 *   2. If the reference a module? e.g. `expo-font`
 *     - Resolve the root `app.plugin.js` file within the module, e.g. `expo-font/app.plugin.js`
 *   3. Does the module have a valid config plugin in the `main` field?
 *     - Resolve the `main` entry point as config plugin
