test(conformance): lower chainsaw parallelism 4->2 to avoid dev etcd overload cascades

Browse Source 
On the small dev VMs, 4 concurrent heavy tests (KubeVirt CDI + Longhorn) spiked
embedded-etcd into leader-changes/apiserver-ServiceUnavailable; with fail-closed
Kyverno admission this cascaded into mass test aborts. 2 lets the full L2/L3 suite
complete in a single clean pass.
