[EDR Workflows][Osquery][Cypress] Fallback for KibanaStatus error response when fetching kibana version (#218240)

This PR fixes an issue that can cause test execution to fail when `await
kbnClient.status.get()` doesn't return the Kibana version. The fallback
now uses the version from `package.json` in that case.

Example failure:
