Since ubuntu 22.10, openssh-server uses socket activation. You can read
more at /usr/share/doc/openssh-server/README.Debian.gz
Copying here:
Socket-based activation with systemd
------------------------------------
By default, socket-based activation is used on systems that use systemd.
The provided ssh.socket unit file sets ListenStream=22. If you need to have
it listen on a different address or port, then you will need to do this as
follows (modifying ListenStream to match your requirements):
mkdir -p /etc/systemd/system/ssh.socket.d
cat >/etc/systemd/system/ssh.socket.d/listen.conf <<EOF
[Socket]
ListenStream=2222
EOF
systemctl daemon-reload
See systemd.socket(5) for details.
If you do not want to use socket activation for ssh on your system, you
can disable socket activation by running:
systemctl disable --now ssh.socket
systemctl enable --now ssh.service
