fix(nemesis): skip truncate large partition nemesis with zero node

due to scylladb/scylladb#20356, need to skip nemesis
disuprt_truncate_large_partition nemesis, because it use
hardcoded scylla-bench command with autoresize rf

Number of nodes in DC increased, this allow to safely
decommission node with tablets feature enabled
