Fix dependency org.apache.beam » beam-it-neo4j

[stefano-ottolenghi]

The dependency com.google.cloud.teleport:it-neo4j doesn't seem to exist, and compilation as of now fails with the following:

[INFO] ------------------------------------------------------------------------

This PR attaches what I think is the right dependency. Compilation succeeds, at least.
