[im-konge]

This PR fixes warnings when building the project:

[WARNING] Discovered module-info.class. Shading will break its strong encapsulation.
[WARNING] Discovered module-info.class. Shading will break its strong encapsulation.
[WARNING] jackson-databind-2.18.3.jar, jackson-core-2.18.3.jar, picocli-4.7.7.jar, snakeyaml-2.0.jar, slf4j-api-2.0.17.jar, jackson-datatype-jsr310-2.15.2.jar, slf4j-nop-2.0.17.jar, jackson-dataformat-yaml-2.15.2.jar define 1 overlapping classes: 
[WARNING]   - META-INF.versions.9.module-info
[WARNING] maven-shade-plugin has detected that some class files are
[WARNING] present in two or more JARs. When this happens, only one
[WARNING] single version of the class is copied to the uber jar.
[WARNING] Usually this is not harmful and you can skip these warnings,
[WARNING] otherwise try to manually exclude artifacts based on
[WARNING] mvn dependency:tree -Ddetail=true and the above output.
[WARNING] See http://maven.apache.org/plugins/maven-shade-plugin/

which is due to having the shaded jar.

[WARNING] log4j-slf4j2-impl-2.24.3.jar, log4j-slf4j-impl-2.24.0.jar define 9 overlapping classes: 
[WARNING]   - org.apache.logging.slf4j.message.ThrowableConsumingMessageFactory
[WARNING]   - org.apache.logging.slf4j.message.package-info
[WARNING]   - org.apache.logging.slf4j.Log4jMDCAdapter
[WARNING]   - org.apache.logging.slf4j.package-info
[WARNING]   - org.apache.logging.slf4j.Log4jMarker
[WARNING]   - org.apache.logging.slf4j.Log4jLogger
[WARNING]   - org.apache.logging.slf4j.Log4jLoggerFactory
[WARNING]   - org.apache.logging.slf4j.SLF4JLoggingException
[WARNING]   - org.apache.logging.slf4j.Log4jMarkerFactory

which is because data-generator is bringing log4j-slf4j-impl and we are using log4j-slf4j2-impl.
