In 1.19.3 Pre-release 2, you can now ignite a Creeper using a fire charge.
However, doing so does not add 1 to a scoreboard value using minecraft.used:minecraft.fire_charge.
See video.
Commands I used are:
/scoreboard objectives add use_charge minecraft.used:minecraft.fire_charge
/scoreboard objectives setdisplay sidebar use_charge
