Fix projectile count being 1 higher on all skills (#7006)

* Fix projectile count being 1 higher on all skills

GGG changed the stat on all their gems from `number_of_additional_projectiles` to `base_number_of_projectiles`so it now included the 1 base projectile all the skills inherently have

* Fix other mods
