E2E: make sure WithVersion is called in elasticsearch.Builder

Otherwise snapshot tests will fail due to different snapshot versions of Elasticsearch being in use at the same time which are not compatible with each other:

"address [10.112.80.116:9300], node [null], requesting [false] discovery result: Failed to deserialize response from handler [org.elasticsearch.transport.TransportService$ContextRestoreResponseHandler/org.elasticsearch.transport.TransportService$ContextRestoreResponseHandler/org.elasticsearch.action.ActionListenerResponseHandler@7a8d374/org.elasticsearch.action.ActionListener$DelegatingFailureActionListener/org.elasticsearch.action.ActionListener$MappedActionListener/org.elasticsearch.discovery.HandshakingTransportAddressConnector$1@5e5489a6/org.elasticsearch.transport.TransportService$$Lambda$5956/0x0000000801b8d658@3e551386/org.elasticsearch.transport.TransportService$$Lambda$5957/0x0000000801b8dac8@5f5d47e8]: remote node [{test-autoscaling-l5nw-es-master-0}{Nrymty08TcCczIDsMZiVsA}{xNbsCxaoSlC0YIVTnaclpg}{test-autoscaling-l5nw-es-master-0}{10.112.80.116}{10.112.80.116:9300}{m}{k8s_node_name=gke-eck-8x-snapshot-603--default-pool-ee6c7ee9-lmpg, xpack.installed=true}] is build [d81727ae3481ed320802a5520d02356aab9aed09] of version [8.3.0] but this node is build [ed782f880f50c2ca0c1c0f4e0..."

is a typically error message that we see as a result.
