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] Detect headless JREs
Crashes caused by the missing AWT dependency come up in the support channels fairly often.
This patch detects the missing dependency and stops the server with a clear error message,
containing a link to instructions on how to install a non-headless JRE.
