Debian-Live can not be build - missing package

[Hans <hans.ullrich@loop.de>]

Dear maintainers,

it is no more possible to build debian-live/stable (bookworm). The reason is a 
missing package in bookworm: grub-efi-amd64-unsigned.

I rechecked and yes, it is no more in bookworm. Of course, I could download it 
as single package and put it in packages.chroot, but there are a lot of 
dependencies, which are also have to be put into and this makes it 
complicated.

I believe a better way is, to change the configuration on the master server, 
so that this package is no more needed. Maybe exchange it to grub-efi-amd64-
signed?

As a workaround (and trixie is already in sight), I changed the settings to 
trixie, which is building like a charm.

Thank you for reading this.

Best regards

Hans
