Adding exclusive notebook pod label

[DharmitD]

The issue resolved by this Pull Request:

Resolves https://issues.redhat.com/browse/RHOAIENG-4546

Description of your changes:

Replace the existing generic dashboard label in the network policy's pod selector with the new exclusive static notebook pod label.

Testing instructions

Deploy DSPO + DSPA.
Deploy ODH Dashboard and Workbenches in the same namespace as that of the DSPA instance.
From the notebook pod, try this curl command:
curl http://<data-science-pipelines-service-hostname>:8888/apis/v1beta1/runs
This command should return a JSON response with details about the existing pipeline runs. If no runs exist, you'll still see the structure of the response, confirming that the API endpoint is accessible and functioning.

Normally I'd say we should have a deprecation period, and think through the timing of this ... but it's unlikely that anyone is actually relying on this today. So I think it should be as easy as what you've got here.

thanks, providing my review based on the label
that would be present in workbenches that would be in 2.11 ODH or above.
