sysutils/dua-cli: update to 2.23.0

New Features

 - display the total count of entries-to-be-deleted in the mark pane.
   This allows to better estimate how much work will be needed to perform
   the deletion.

   For example, when marking 3 items for deletion, previously one would see
   3 items marked, but now one will see all items and sub-items, like
   120kitems marked`, which reflects the work that will be done much more
   precisely.

 - Add total size to header bar and change to aggregate, human-readable item count.
   This changes the display from (2034 items) to
   (2k items, 213 MB), providing an overview of the total amount
   of storage used along with the total amount of files on a particular
   hiearchy level.

Bug Fixes

 - single files will not cause IO error
   Running dua <filename> will once again provide size information
   about that filename.
