Support for an additional java version (java11-graalvm-ce)

### Enhancement Type

New server type

### Describe the enhancement

Hello,
I would like to know if it was possible to add a java version in tag for the itzg/docker-minecraft-server image.
I use a Minecraft server software (CatServer) in 1.16.5 and I would have to use a version of java 11 because java 8.
Of all the java versions on offer, I really prefer java graalvm-ce because after several tests I've carried out, it's the one that offers the best cpu / ram performance.
Unfortunately, itzg/docker-minecraft-server images with graalvm-ce only exist in java 8 (outdated) and java 17 (too recent).
Would it be possible to add the itzg/docker-minecraft-server:java11-graalvm-ce image?

Regards

Start by reviewing how the existing Java 8 and Java 17 GraalVM CE variants are defined for the itzg/docker-minecraft-server image. Add the java11-graalvm-ce variant and verify that the requested image tag can be built and published consistently with the other Java versions.
