I think this is the wrong URL, since it redirects here:

https://developer.mozilla.org/en-US/docs/Trash/Apps_zone?redirectlocale=en-US&redirectslug=Web%2FApps%2FApps_zone

From what I gather, it should end up here:

https://developer.mozilla.org/en-US/Apps

Will probably just merge this PR, though, and we can tweak this in the near future
