Export the k8s logs of graphscope helm test and upload to artifact when the helm test failed

[dashanji]

What do these changes do?

As titled.

[sighingnow]

Export logs for k8s-ci as well.

Don't touch the graphlearn submodule.

[dashanji]

I'm sorry we can't dump the logs of the k8s-ci test at present, and current kubernetes-export-logs can only support dumping all logs at a time rather than a period of time. As all k8s resources are managed by the coordinator, and whether the pytest succeeded or failed, the k8s resources will be deleted after that.

gss.yaml also has a helm test.
