Subject: [PATCH] Add Release Workflow (#3)

* Cosmetics

* Get rid of @implNote as it creates issues with javadoc

* Make changes in order to be able to deploy to Maven Central from local

* Rename

* Use artifact id

* Remove GPG keyname

* Move Java version to environment variable

* Add release workflow

* Not needed

* Hard code as this seems to work
