Public bug reported:

The firmware blobs for bluetooth on the Pi Zero 2W are correctly named
(with .zst extensions) in the current questing linux-firmware-raspi, but
the links *to* them from /lib/firmware/brcm are lacking the .zst
extension. This results in the module failing to load the firmware
correctly.
