### Description

When deploying Kubeflow Workspaces version `v2.0.0-beta.1` by default the JupyterLab Workspace is hidden from the WS create flow:

This is due to the filterRules that landed with #1357 and they way that our samples are set up:

https://github.com/kubeflow/notebooks/blob/18035691b8099f4bcdbb684c3d4b7ba047ab13c0/workspaces/controller/manifests/kustomize/samples/jupyterlab_v1beta1_workspacekind.yaml#L65-L76ry

It's quite nice to see the feature working, however I could see that this could confuse people that want to try out the beta release. Also we've been stressing that those are only example configurations, however the JupyterLab sample is our most comprehensive one (showcasing redirects etc.), so we should most likely make that visible by default.
