- Add `recentupdated` to the `OrderByMap`.
- Add integration testing for organization and user repository sorting.
- Resolves #5612
- Regression from 12e23ee199 where the
`recentupdated` case was not added to the map, but was handled
seperately as a fallback. The regression came into affect when
5a0bc35799 also relied on this map but
didn't handle the `recentupdated` case.
