Here is the difference between the two cards, as of the last sync:

  # in Org repo
  $ git diff release_9.6.11..origin/emacs-sync -- doc/orgcard.tex
  diff --git a/doc/orgcard.tex b/doc/orgcard.tex

So there are some adjustments for the Emacs tree (e.g., don't depend on
Org's generated org-version.tex and include Emacs's generated
etc/refcards/emacsver.tex).

You can just update the card on Org's side; the changes will be
propagated.
