I see on review that your patch does fix any broken override files, by
virtue of replaying the same upgrade code if upgrading from 1ubuntu6.
There are some corner cases where that might not be desirable, but as
these are all pre-release versions I think it's ok to ignore these in
favor of landing the fix more quickly.

Title:
sshd port migration is missing two config lines from jammy to kinetic
Status in openssh package in Ubuntu:
In Progress
Status in systemd package in Ubuntu:
Invalid
Bug description:
The automatic migration script from jammy to kinetic generates a
invalid file for sshd that systemd refuses to read. Manual addition of
two lines is required for a functional sshd with a custom port.
This bug can be considered the opposite of
https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1990863 . They
want to have sshd keep managing the socket while I want to try letting
systemd do that.

# Instructions
- Configure /etc/ssh/sshd_config to port 2222 in 22.04
- Upgrade to 22.10 with sudo do-release-upgrade -d
- Accept overwriting /etc/ssh/sshd_config with the new version
- Attempt to ssh into the machine
# Expected behavior
systemd should listen on port 2222 and start sshd.

$ cat /etc/systemd/system/ssh.socket.d/override.conf

# Analysis
The migration script must be missing the `[Socket]` line and the next one.
sshd works after I added those two lines manually. Either the migration script
never worked or systemd changed the syntax in the meantime.
