leds: st1202: Refactor st1202_led_set() to use !! operator for boolean conversion

st1202_led_set function now uses the !! operator to convert the
enum led_brightness() value to a boolean active state, which is then
passed to the st1202_channel_set() function. This change maintains the
existing functionality.
