Include the OptaPlanner version number calculation and version bump in the Jenkinsfile.deploy and Jenkinsfile.promote

As part of the changes realized in:
https://issues.redhat.com/browse/KOGITO-4167

we can now add the proper dependency to OptaPlanner in kogito-apps.

The dependency will added like this, in the kogito-apps/pom.xml

<properties>
     <version.org.optaplanner>8.2.0-SNAPSHOT</version.org.optaplanner>
</properties>

and in the

  <dependencyManagement>
      <dependency>
        <groupId>org.optaplanner</groupId>
        <artifactId>optaplanner-bom</artifactId>
        <version>${version.org.optaplanner}</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
</dependencyManagement>

By doing this the proper version passed by the Jenkinsfile.deploy/Jenkinsfile.promote will be taken.

However it was stated https://github.com/kiegroup/kogito-apps/pull/591#pullrequestreview-570250826 it looks that these scripts might require some tuning for doing the calculation of the value of the OPTAPLANNER_VERSION variable to be passed to the maven script.
