Support 1.20.6

[minamikana-git]

Minecraft Development for IntelliJ plugin version

latest

Description of the feature request

Currently, Minecraft 1.20.4 is supported up to 1.20.6, but now that 1.20.6 of PaperMC has been released, 1.20.6 should be supported as well.

[RedNesto]

Paper 1.20.6 builds are experimental, I'd rather wait until it becomes stable before including them in the creator.

It is better that people begin already now to migrate their plugins to 1.20.5/1.20.6 than in a few days/weeks

[RedNesto]

We don't need to do anything else for supporting 1.20.6 AFAIK, only the creator needs to be aware of the new version.

[John-Development]

Might be unrelated, but fabric mixins also seems broken in 1.20.6, the plugin cant find any @Inject method that were working in previous versions.
