Enhancement Type

New server type

Describe the enhancement

It would be great to add a new server like Cleanroom (https://github.com/CleanroomMC/Cleanroom), it's a Forge fork, for Minecraft 1.12.2. It can run on Java version 21+.

In the meantime you might be able to set FORGE_INSTALLER_URL to point to their installer artifact in GitHub:
