Bug: org-anniversary dates not exported to iCalendar [9.4.6 (9.4.6-3-g37f69b-elpaplus @ /home/marcus/.emacs.d/elpa/org-plus-contrib-20210531/)]

[Marcus Zibrowius]

I have an org-file with entries of the form

* Abel's birthday party
  <2023-11-13>

and with entries of the form

* Abel Jacobi
%%(org-anniversary 1978 11 11) Abel %d

Both types of events show up in my agenda view in emacs. However, when I
export to ics (e.g. org-export-dispatch > [c] Export to icalendar > [f]
Current file), only the former type of entries is included in the
resulting ics-file.

User "phils" on the (emacs) StackExchange website suspected this is a bug and
directed me here.  Following their advice, I tried using diary-anniversary
instead of org-anniversary.  With this change, the event does get exported
correctly to icalendar, but it no longer shows up in my agenda view in
emacs. (Also, %d gets exported verbatim rather than converted to the
appopriate integer.)
