Fix Cybersun Pen Damage (#1459)

# Description

Sets the Cybersun pen's throwing damage to be the same as its melee
damage and also inflict embedded passive damage.

Because the Cybersun pen inherits from `PenEmbeddable` that manually
sets its own `DamageOtherOnHit` damage because it's not a melee weapon,
the Cybersun pen's throwing damage didn't inherit the melee weapon
damage and it was low compared to its melee damage.
