How has this been tested?

1. Fresh /e/ install

2. Enable ADB and root

3. Flash the Apps version from the GitLab CI pipelines of this MR

4. Replaced the default system microG APK with an old one (v0.2.14 without EN). Need to sign it with test

   asigner sign --key platform.pk8  --cert platform.x509.pem --out microG-noEN.apk play-services-core-withMapbox-withoutNearby-release-unsigned.apk 
   adb push microG-noEN.apk /system/priv-app/GmsCore/GmsCore.apk

5. From Apps, install microG EN as usual

6. Replaced the microG EN version install by Apps by an old on (v0.2.14 with EN)

   adb push play-services-core-withMapbox-withNearby-releaseTest.apk /data/app/com.google.android.gms-GOaRJO3aNVreH3DG8tv6Pw==/base.apk

7. Then I open Apps > Updates: the update appear as expected! And download&install starts automatically.
