org-element--cache-sync: Another take on false positive warnings
* lisp/org-element.el (org-element--cache-sync): Suppress silent edit
warnings for Emacs <28. In older Emacs, Emacs internal functions can
modify `buffer-chars-modified-tick' and cannot be distinguished from
dangerous edits under `inhibit-modification-hooks'. Some of the
functions even have the same footprint with the edits we want to
avoid.
