java-library and java-platform: create default publication when maven-publish is applied

[gabrielittner]

Expected Behavior

Having

plugins {
  id "java-library"
  id "maven-publish"
}

or

plugins {
  id "java-platform"
  id "maven-publish"
}

should automatically create a publication without requiring further configuration by the user.

Current Behavior

Currently you need to add

publishing {
    publications {
        create<MavenPublication>("myLibrary") {
            from(components["java"])
        }
    }
}

and

publishing {
    publications {
        create<MavenPublication>("myPlatform") {
            from(components["javaPlatform"])
        }
    }
}

respectively to the above configuration to enable publishing.

Context

Creating publications by default would match both the current behavior of the java-gradle-plugin and the general convention over configuration approach. The user already indicated that they want to publish the library/platform so they shouldn't need to repeat that same piece of code everytime.
