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] Don't use level random in entity constructors
Paper makes the entity random thread-safe
and constructing an entity off the main thread
should be supported. Some entities (for whatever
reason) use the level's random in some places.
