Documentation page on using Kueue to run Notebook

[mimowo]

What would you like to be added:

A documentation page under https://kueue.sigs.k8s.io/docs/tasks/run/ showing how to use Kueue to run Kubeflow Notebook.

Then we should also update the main README and reference the page from the "Features overview / Integrations" point.

This is a follow up to #3352

Why is this needed:

To showcase Kueue is supporting the running of Notebook. To guide users how to do it.

Completion requirements:

This enhancement requires the following artifacts:

• Docs update

The artifacts should be linked in subsequent comments.

Since the "kueue. x-k8s. io/ queue-name" label is not being added by the notebook-controller to STS, the notebook integration is not working out of the box.

Just tested it out, and looks like a small update in NB controller is needed.

I'll create a PR with NB controller to add NB CR labels to SS, and once it is done can create a doc PR in here.

Awesome, thanks!
