Fix Maven again

[iNoles]

I have noticed that three JVM folders are not being uploaded to the Maven repo. I will be checking the snapshot once it is finished.

What do you think about adding this into publication.gradle.kts file? So we don't have to manually add this into the subproject gradle file?

publications {
        if (project.name.substringAfterLast("-") == "jvm") {
            create<MavenPublication>("maven") {
                from(components["java"])
            }
        }
    }

Something like

I think that would be much better.
