Some of the quickstarts do not use the correct WildFly version

The org.wildfly.plugins:wildfly-maven-plugin is used in several of the quickstarts, but the incorrect WildFly version is used. In some cases it's not used at all which would default to the current version in jboss-stacks. In other cases it's using the version.widfly.bom which is set to 19.0.1.Final. That version of WildFly dos not exist.
