fix(gemini-test-nodes): Increase the number of nodes in the test DB f…

…rom 3 to 4 As observed in a couple of new gemini runs [#6](https://argus.scylladb.com/tests/scylla-cluster-tests/f0c504cb-4bf5-47d4-a6bb-f0a102ec7fe4) [#7](https://argus.scylladb.com/tests/scylla-cluster-tests/26276989-e33c-40f1-9e94-788a4d824344) [#4](https://argus.scylladb.com/tests/scylla-cluster-tests/193e537e-e025-4857-86db-2156cd870fc3) [#2] https://argus.scylladb.com/tests/scylla-cluster-tests/41d1290a-1998-4bf4-9d15-4b21ad98cff9 Gemini's failures are caused by not having enough nodes in the test DB when cluster in run with Tablets, and by that we cannot establish quorum. This PR increases the number of nodes in the test DB to 4 in all relevant cases with nemesis. Signed-off-by: Dusan Malusev <[email protected]>
