After kernel commit 907bc9268a ("Input: atkbd - map F23 key to support default copilot shortcut")
Fn+F5 combination (switch touchpad on/off) stopped working correctly.
Fn produces F23, it is probably a bug in BIOS, ther eis no "Copilot" key.
It was ignored before that commit, but now we have to remap it here in hwdb.
This workaround is similar to systemd commit d2502f5
("hwdb/keyboard: Map FN key on TUXEDO InfinityFlex 14 Gen1")

Files in this directory specify a description of hardware devices, in the form of mappings from modalias-like keys (which identify specific hardware devices) to udev properties. Files in this directory are not read by udev directly. Instead, man:systemd-hwdb(8) compiles them into a binary database. See man:hwdb(7) for an overview of the configuration file format, and man:systemd-udevd.service(8) for a description of the udev daemon. Use 'systemd-analyze cat-config udev/hwdb.d' to display the effective config.
