arche-type parent not available in maven

The translator archetype was updated for 9.0.0, but the parent was not pushed to maven:

Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:3.0.1:generate (default-cli) on project standalone-pom: The desired archetype does not exist (org.jboss.teiid.arche-types:translator-archetype:9.0.0)

The docs should also be updated to define the available archetype versions.
