🐛 After upgrading an Expo app to SDK 56, Expo config evaluation fails when using the `react-native-ble-plx` config plugin.

Prerequisites

• I checked the documentation and FAQ without finding a solution
• I checked to make sure that this issue has not already been filed

Expected Behavior

• We upgrade to Expo SDK 56 and successfully run npx expo-doctor with no errors.
• App builds successfully

Current Behavior

During Expo SDK 56 upgrade I discovered an issue with an import of expo/config-plugins.
While running expo-doctor command I receive an error:
node_modules/expo/bin/cli config --json --full exited with non-zero code: 1

Investigating further I found an error:

Skipping config plugin check: Cannot find module '@expo/config-plugins'
Require stack:
- node_modules/react-native-ble-plx/plugin/build/withBLE.js
- node_modules/react-native-ble-plx/app.plugin.js

The plugin currently imports:
from '@expo/config-plugins'

Expo SDK 56 recommends using the Expo sub-export instead:
from("expo/config-plugins")

Adding @expo/config-plugins directly to the app (devDependencies) works around the crash, but expo-doctor warns that this package should not be installed directly.
