chore: reference ghcr.io images in workspacekind yaml (#305)

Given we have migrated all our images from docker.io to ghcr.io - our `notebooks-v2` branch should reference the "proper" container registry.

This commit updates the code to use:
- `ghcr.io/kubeflow/kubeflow/notebook-servers`

Affected areas:
- `jupyterlab_scipy_180` and `jupyterlab_scipy_190` `imageConfig` entries
- various test files
