Revert "Add support for exporting to Google Play Instant"

This reverts commit 12ad9ed4e0b199ac637c3c7b0b8a8dd4f901e1f1.

Shortly after the feature was merged, we received news that Google will shut down Instant Apps in December 2025. Since this feature is being discontinued soon, there’s no value in keeping it for just a few months.
