Downloading modpack error (Unexpected content type 'application/x-amz-json-1.0')

[alexandros-aristovoulos]

Docker compose yaml used to start a minecraft container with the Medieval MC Modpack :

  minecraft:
    image: itzg/minecraft-server:java8
    ports:
      - 25565:25565
    environment:
      EULA: "TRUE"
      TYPE: CURSEFORGE
      CF_SERVER_MOD: https://mediafilez.forgecdn.net/files/4111/179/Medieval+MC+Server+Pack+FABRIC+1.19.2+v12.5.zip
    tty: true
    stdin_open: true
    restart: unless-stopped
    volumes:
      - /home/NAS/Minecraft:/data

results in the following error:

Tested with a couple of different modpacks and they all have the same issue

Weird, AWS S3 claims the content is JSON (application/x-amz-json-1.0) even though it's a zip file coming back. So much for enforcing the accepted content type -- I'll revert #1837 😒.
