Allow using Java 17+ Versions

[heavy ingot]

Allow the usage of Java 17+ versions such as Java 21. This would increase the performance of the client and also allow for the usage of Generational ZGC, which is a low latency garbage collector that eliminates stutters and has pause times of under 1ms. This would decrease stutering on the client and stabilize FPS. On PrismLauncher / MultiMC this can be done by simply skipping "Java Compatibility Checks" and on the normal minecraft launcher you can delete the JavaCheck.jar file to do so, though on Lunar Client this cannot be done.

Good idea that would really help lunar performance

lunar by default uses jdk 17, but I doubt they will allow using different jdks for some random reason
