Even though it's not actually used anywhere in the English or non-English content, there's still a reference to SimpleBadge in the English (and Spanish) content here (and here). @chrisdavidmills Can we remove those references?

PR opened to fix the English version at least. I don't know if we really care about the es version if it not an active locale?

Sigh. That means that my tooling for figuring out which ones get rendered isn't working. I'll have to revisit to try to figure out what's going on.

Thanks @chrisdavidmills! No, I don't think we care about the es version since it's not active.
