Remove "elasticsearch-basics" test

This was broken in the new Elasticsearch 8.0, but while looking at how to fix it (disabling auth, for starters) I realized it wasn't really providing any real value anymore, so instead of trying to adapt it to the updated API requirements of 8.0, I chose to remove it instead.
