Try the following code. It should archive any repeated task once it is
marked DONE.

(defun org-archive-repeated-task (arg)
  "Add a copy of the recurring task marked DONE to archive."
  (when (and (eq (plist-get arg :type) 'todo-state-change)
             (string= (plist-get arg :to) "DONE")) ;; The state is changed to DONE
    (let* ((pos (plist-get arg :position))
           (repeater (org-with-point-at pos (org-get-repeat))))
      (when repeater ;; Only consider tasks with repeater timestamp anywhere in the task body
        (my/org-archive-without-delete)))))
(add-hook 'org-trigger-hook #'org-trigger-doing)

Best,
Ihor
