A better fix would be to make Godot's export code properly parse the
tag over multiple lines (and maybe even use XMLParser instead of doing
it ad-hoc?).
As for the APK names, we could alternatively pick the first .apk found
in the `debug` and `release` folders without expecting a specific name.
Fixes#32414.
The application module `app` serves double duties of providing the prebuilt Godot binaries ('android_debug.apk', 'android_release.apk') and the Godot custom build template ('android_source.zip').
