Move the artefact data-test-les-arbres-redis-1.1.gz to packages

Recently our benchmark pipeline failed because the Nexus behind maven-eu.nuxeo.org was inaccessible (Connection timeout mostly).

To remedy to this we would like to put this artefact on packages.nuxeo.com in the maven-public-releases repository.

The benchmark pipeline should be updated after this move to take the artefact from packages.nuxeo.com.
