Fix SWCK oapserverconfig e2e version mismatch causing pod restart timeout

The SWCK operator matches OAPServerConfig to OAPServer by spec.version.
The OAPServer uses version "latest" but the oapserverconfig-demo.yaml
has version "9.5.0", so the operator never applies the config and the
OAP pod is never restarted, causing the test to timeout.
