fix(display): use [pi5] config.txt section instead of [cm5]

Browse Source 
Rex's Trixie images use [pi5] for the CM5 display overlays
(clockworkpi-uconsole-cm5, vc4-kms-v3d-pi5). The nixos-uconsole
module generates [cm5] which the firmware may not apply on
some CM5 EEPROM configurations. Adding explicit [pi5] section
ensures the display overlays are always loaded.
