Bug#1065567: timedatectl does not recognize ntpsec

It looks like Systemd's timedatectl does not recognize ntpsec. Using
it results in 'NTP service: n/a':

$ timedatectl
               Local time: Wed 2024-03-06 12:35:32 EST
           Universal time: Wed 2024-03-06 17:35:32 UTC
                 RTC time: Wed 2024-03-06 17:35:32
                Time zone: America/New_York (EST, -0500)
System clock synchronized: yes
              NTP service: n/a
          RTC in local TZ: no

According to <https://wiki.debian.org/DateTime#Installing_NTP>, ntpsec
is an option for Debian 11 and below; and default for Debian 12 and
above.

I searched for an upstream bug at <https://github.com/systemd/systemd>
(is that the right place?), but there were no relevant hits. See
<https://github.com/systemd/systemd/issues?q=is%3Aissue+ntpsec>.

Also see <https://lists.debian.org/debian-user/2024/03/msg00145.html>.
That's the debian-users mailing list discussion with GW's comment.
