hwdb: add force-release volume key quirk for Lenovo ThinkBook 16 G7 ARP (21MW)

Browse Source 
The Embedded Controller (EC) on the Lenovo ThinkBook 16 G7 (Product
Name: 21MW) fails to transmit PS/2 break codes (E0 B0) for Volume Down
(ae) and Volume Up (b0) upon physical key release after auto-repeat
(long press). This causes the volume keys to become logically stuck
down in the Linux input subsystem. Adding the '!' force-release flag
instructs udev/evdev to automatically synthesize a release event
immediately upon receiving the keypress.
