itzg/docker-minecraft-server

AI Summary: The task is to debug a Dockerized Minecraft server image. The `itzg/minecraft-server` image's Modrinth integration is failing to correctly utilize the `MODRINTH_LOADER` environment variable when using a custom server JAR and the `TYPE: CUSTOM` setting. The issue stems from the helper script not properly handling the loader specification within `MODRINTH_PROJECTS`. The solution involves either modifying the helper script to correctly parse the `MODRINTH_LOADER` variable when used with `TYPE: CUSTOM` or finding an alternative way to specify the loader for Modrinth downloads in this context.
