ST6RI-849 Adds a Github Actions workflow for releases

Adds a release build workflow, triggered by publishing a release record in the repository or by executing the workflow manually.

This build is different to the normal builds in the following ways:

 - It skips test execution (it is expected a normal build already ran successfully for this commit before the release is finalized)
 - It skips verification of the generated library index (again, it is expected a normal build was already run)
 - A Maven version task is executed to remove the -SNAPSHOT version.

Important to note: if the process is executed a second time without changing the base versions, the publish process will fail, as release builds cannot be overwritten in Github Packages.
