Fix issue #1588

Starting from API30 (Android 11), your Android app has to list all apps it interacts with.
We should add this to manifest:

<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"/>

Oh okay yes, we can add this by adding to the config.xml file:

        <config-file parent="/manifest/" target="app/src/main/AndroidManifest.xml">
            <uses-permission android:name="android.permission.QUERY_ALL_PACKAGES" />
        </config-file>

But it seems Google is quite strict with this: https://support.google.com/googleplay/android-developer/answer/10158779#zippy=%2Cpermitted-uses-of-the-query-all-packages-permission. But I think this should fall under the permitted uses?

LGTM thanks.
