Overwrite the existing map with the new map.

[morgernite]

Overwrite the existing map with the new map.
I ran version 1.21 with Fabric and placed an old map in the world folder, but it was overwritten with a new map every time I started the server.

VERSION: 1.21

volumes:
  # attach the relative directory 'data' to the container's /data path
  - ./data:/data
