Updated version # in run-converter to match version # in pom.xml

The run-converter script was failing with the error message:

  couldn't find target/concrete-agiga-2.0.0-SNAPSHOT.jar and target/concrete-agiga-2.0.0-SNAPSHOT-jar-with-dependencies.jar jars

because the concrete-agiga version number in the run-converter script
did not match the concrete-agiga version number in pom.xml.
