Deleted references to Save Backup Mod from docker-compose-steam.yml, docker-compose-gog.yml, and the README file. This removal reflects that the Save Backup Mod is no longer enabled or supported in this application.
Incorporated the Unlimited Players Mod in the docker compose files for both steam and gog versions. This mod allows for a dynamic number of players to join, and the number can be set via the UNLIMITED_PLAYERS_PLAYER_LIMIT environment variable. Additionally, new configuration and manifest files were added for the UnlimitedPlayers mod.
Docker-related files have been renamed and updated to better suit the GOG and Steam versions of the game. The README.md has been significantly expanded, improving explanation of server setup and usage details for each version.
