Subject: [PATCH] fix: special handle thrown eggs for projectile hit checks
 (#4728)

Cancelling the ProjectileHitEvent will not cover for thrown eggs spawning chickens due to how Bukkit has these events structured. The provided patch calls the same code used for normal projectiles in the specialized egg event to prevent unwanted chickens from spawning on other plots.
