Fix Ender-3 V3 KE nozzle switching (#13438)

Fix Ender-3 V3 KE nozzle switching by adding printer_variant

The four Creality Ender-3 V3 KE 0.X nozzle profiles were missing the
printer_variant key, so OrcaSlicer could not map a UI nozzle selection
to a specific profile and reverted every choice to 0.2mm. Add the
matching printer_variant to each, following the CR-10 SE / K1C pattern.
