Windup-maven-plugin create nightly snapshot build

In the nightly snapshot nightly builds chain, the windup-maven-plugin project is missing so the quick-start project build fails since it's not able to retrieve the artifact org.jboss.windup.plugin:windup-maven-plugin:jar:4.2.0-SNAPSHOT.

Add a new build for windup-maven-plugin project at the end of the windup-snapshot-deployment deployments
