🌍 SpacePvP Update: New Localization System

Added support for 18 languages: UA, EN, RU, DE, PL, FR, IT, JA, KO, CS, SK, ZH, ES, AR, BG, NL, RO, BR, TR.

⚠️ Important for existing users:

If you already have a translation configured in the old messages.yml file, you need to move it to the new system, as the old file is no longer used:

1. In config.yml, set the desired language in the language field (e.g., en_US or uk_UA).
2. Copy your text from the old messages.yml.
3. Transfer it to the corresponding new file in the langs/ folder (e.g., langs/en_US.yml).
4. Reload the config with /spacepvp reload.

Configuration example in config.yml:

general_settings:
  language: "en_US"
