Make throwable star damage stamina (#23527)

* feat(star.yml): make throwable star damage stamina

* feat(Components): add new StaminaTresholdDamageOnEmbedComponent

* feat(SharedProjectileSystem): update system with new events to change
stamins treshold on embeed projectile remove / add

* feat(StaminaSystem): update system with new subscriptions

* feat(throwing_stars): update yml with new component

* feat(StaminaDamageOnEmbed): add stamina damage on embeed

* cleanup unused / ajust numbers

* fix(StaminaSystem / OnEmbedComponent ) apply requested changes

* Rest of the review

* another warning
