Asset Browser: Remove catalog deletion confirm prompt

This confirmation popup was added when deletion was a destructive action that
would be written to disk immediately, with no way to undo. Now we only write
such changes to disk on .blend file save, plus there's undo/redo support for
catalog edits now. In such cases confirmation popups should be avoided.
