Use net.kyori.ansi for console logging (#9313)
Uses the new ANSIComponentSerializer introduced in Adventure 4.14.0 to
serialize components when logging them via the ComponentLogger, or when
sending messages to the console.

This replaces the old solution which uses legacy jank and custom color
conversions, with a new library that handles the conversion and config

Subject: [PATCH] Fix cancelling ProjectileHitEvent for piercing arrows
Piercing arrows search for multiple entities inside a while
loop that is checking the projectile entity's removed state.
If the hit event is cancelled on the first entity, the event will
be called over and over again inside that while loop until the event
is not cancelled. The solution here, is to make use of an
already-existing field on AbstractArrow for tracking entities hit by
piercing arrows to avoid duplicate damage being applied.
