  Subject: [PATCH] Show button to open knetattach inline with URL nav on
   Remote:// view

  In conjunction with
  https://invent.kde.org/frameworks/kio/-/merge_requests/260,
  the net result is to hide the knetattach launcher in the view, and show
  it inline with Dolphin's URL navigator toolbar when viewing the
  remote:// view, just like how we add an "Empty Trash" button when
  viewing trash://.

The backport ensures that even with frameworks << 5.78 only one network
button is shown.
