Attack indicator 2.0

Added

• Integrated MiniMessages for all plugin text, allowing for more advanced formatting options.

Changed

• Complete rework of the plugin's core mechanics for better performance and stability.
• The plugin is now significantly more lightweight.
• Replaced the old Armor Stand-based indicator with the new Display Entities system, introduced in Minecraft 1.19.4. This should provide a much smoother and more reliable experience.
• Most previous configuration settings have been retained to ensure a smooth transition.

Fixed

• Resolved a major bug where the indicator (an Armor Stand) would not be removed properly, causing it to get stuck in the sky.
