Create new category: "Religion"

Originally requested at: https://forum.f-droid.org/t/nsfw-flag-incorrectly-added-to-bible-and-quran-apps/33401/62 List of apps: https://github.com/offa/android-foss/issues/569#issuecomment-3440596296

Edit: They requested for Anti-Feature. Personally I don't think Anti-Feature flag is appropriate for such apps. What do you think about new category instead?

IoD already has such category.
