Things needed:

• adjust gradle build configuration
• adjust the release github workflow

The inspiration could be taken from how it is done in https://github.com/Smarteon/loxone-java

• https://github.com/Smarteon/loxone-java/blob/master/build.gradle.kts - note the vanniktech maven publish
• https://github.com/Smarteon/loxone-java/blob/master/.github/workflows/loxone-java-release.yml

However this project is kotlin multiplatform, so studying the documentation for publishing plugin is wise.

The secrets and variables are already ready in github.
