org-priority: Fix SPC handling for numeric priorities (bug#52341) 

* lisp/org.el (org-priority): When reading numeric priorities, provide
special handling of SPC so that it clears the priority, as advertised.

If the user has configured numeric priorities and tries to clear a
priority by inputting SPC at the prompt, org-priority feeds " " to
string-to-number and ends up with 0 instead of the ?\s (32) that's
used downstream to signal "remove".  Explicitly check for " " and
translate it to ?\s.
