This is very strange.
zz-update-grub is just a normal dpkg conffile. We don't do anything
special with it.
And according to our git, it wast last changed 2021.

I guess to fix that with dpkg you would need to completely purge the
package and then reinstall. But please make a backup of
/etc/default/grub

Or you could check if the dpkg-dist is the correct one and just rename
that.

Also check /etc/kernel/postrm.d/
Looks like there it's also missing or with the .dpkg-dist extension.
