DEV: Move user-profile-secondary outlet (#28398)

Move it into the preceding `dl` element and remove the `div` wrapper.

The two plugins that use this outlet:
* d-follow - actually jumps through hacky hoops to get its elements into that `dl` anyway
* d-gamification - would look better if its element was in that `dl`
