REMOVE_OLD_MODS deletes all mods downloaded by MODRINTH_MODPACK

[xdinterface]

Describe the problem

When REMOVE_OLD_MODS is set to true and the Option MODRINTH_MODPACK is used to download mods, the mods are getting deleted before the server starts resulting in the server starting without mods.

I need to disable that behavior, but in the meantime please don't combine those options. Modrinth platform support already takes care of cleaning up mods it manages.

Unrelated, I noticed that your WHITELIST_FILE needs to be a container visible path, such as /data. The path you're providing, /home/hades/minecraft/cb/whitelist.json, is a host path. So it looks like it needs to be /data/whitelist.json...which is actually extraneous to declare because that's where the Minecraft server will locate the file in the first place.

This needs to be addressed for AUTO_CURSEFORGE also.
