DevSettingsActivity is not removed in release builds of Android

[SanjayDevTech]

Description

I am using Expo managed workflow to build apps. But I do think this issue is not related to expo alone, so putting it here.

On Debug mode we can open the dev settings page by typing "m" in the console. I have seen DevSettingsActivity added to the AndroidManifest on debug app.

But when I build the release apk (by using github actions not eas cloud, but I think both doing the same), I still seeing the DevSettingsActivity added to AndroidManifest.

I saw there is a comment

react-native/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/devsupport/AndroidManifest.xml

Lines 5 to 8 in dc2000c

	<!-- This activity will be removed for release builds -->
	<activity android:name="com.facebook.react.devsupport.DevSettingsActivity"
	android:exported="false"
	/>

mentioned like it will be removed in release.

Currently to remove I am using a config plugin

const { withAndroidManifest } = require("@expo/config-plugins")

module.exports = function androiManifestPlugin(config) {
  return withAndroidManifest(config, async config => {
    const androidManifest = config.modResults.manifest;

    const application = androidManifest["application"][0];

    application.activity = application.activity.map(
      activity => {
        if (activity.$["android:name"] !== "com.facebook.react.devsupport.DevSettingsActivity") return activity;
        activity.$["tools:node"] = "remove";
        return activity;
      }
    )

    return config
  })
}

Steps to reproduce

1. Create any React Native App
2. Build it in Release mode
3. Analyse the APK using any APK analyser app found in playstore.
