ncp-dist-upgrade (bullseye to bookworm) does not contain bootloader for RPI5

[schuck23]

I updated my nextcloudpi installation on a RPI4 from bullseye to bookworm (see https://help.nextcloud.com/t/problems-migrating-nextcloudpi-from-raspberry-pi-4-to-raspberry-pi-5/219742).

As bookworm is the minimum for RPI5, I was thinking that the update to bookworm on the SD card should make the installation usable in an RPI5. Obviously this is not the case, as "bcm2712-rpi-5-b.dtb not found " is displayed in the bootloader on the RPI5 (see "Path 2" in the provided link).

My understanding is that ncp-dist-upgrade should ship all necessary files to make the installation work on all RPI versions currently supported by the os version.
