Dear Maintainer,

I upgraded openssh-server yesterday on bookworm and I believe it is the
upgrade that caused a change in the configuration file that disabled
GSSAPIAuthentication. Before the upgrade it worked (I believe I had it
explicitly enabled in in sshd_config) and after the upgrade it was
commented out (it doesn't work).

Fortunately I was able to log into the upgraded using different means of
authentication, but still such change of the configuration shouldn't
happen during an upgrade.

I am not 100% the configuration file was edited/replaced during the
upgrade (I am browsing the Debian openssh package git repository), but I
can't see any other reason this has changed.
