Sort issues and pulls by recently updated in user and organization home (#22925)

The main purpose of these home pages should be getting an overview of
what's going on or needs attention. Recently updated is a better default
than newest for that purpose, to avoid missing active issues and pulls
that were not created recently.

The default sorting order in repository issues and pulls remains newest.
Repositories in an organization are already sorted by recently updated.
