bug(os): wireless network issues due to upstream `linux-firmware` change

[oklopfer]

In a recent update upstream, the linux-firmware package was broken out into several subpackages:

linux-firmware-amd-graphics
linux-firmware-broadcom-wireless
linux-firmware-intel-graphics
linux-firmware-intel-misc
linux-firmware-intel-wireless
linux-firmware-marvell-prestera
linux-firmware-marvell-wireless
linux-firmware-mediatek
linux-firmware-mellanox-spectrum
linux-firmware-misc
linux-firmware-netronome
linux-firmware-nvidia-graphics
linux-firmware-qlogic
linux-firmware-qualcomm-graphics
linux-firmware-qualcomm-misc
linux-firmware-qualcomm-wireless
linux-firmware-realtek

Due to the way this has currently been shipped, users may lose wireless connectivity abilities. In order to resolve this issue, either install the specific firmware packages relating to your system, or as a catch all, one may run:

rpk S
sudo apt install linux-firmware --install-recommends

Of course, this will require a functioning network connection; an ethernet connection will suffice.

We will include all firmware packages in our next snapshot images, but for an individual system, this may be unnecessary; we therefore are not shipping a hotfix for this at this time, as it is a case-by-case basis. We apologize for any breakage caused by this upstream change.
