Running the new release upgrader tarball from the link you provided seems to have fixed the issue. After removing the unused package I still have the linux-raspi meta packages installed:
$ dpkg -l | grep linux | grep "5\.4\.0\."
ii linux-headers-raspi 5.4.0.1015.50 arm64 Raspberry Pi Linux kernel headers
ii linux-image-raspi 5.4.0.1015.50 arm64 Raspberry Pi Linux kernel image
ii linux-raspi 5.4.0.1015.50 arm64 Complete Raspberry Pi Linux kernel and headers
