Link to IceSat2 tutorial gives a "404 error"

[carlnorlen]

When I try to navigate to the IceSat2 tutorial on the Cloud Cookbook website I get a "404 error". Has that tutorial been removed or does the link need to be updated?

I checked https://nasa-openscapes.github.io/earthdata-cloud-cookbook/external/IS2_cloud_Landsat_integration.ipynb and the notebook is no longer in the external path. I'm not seeing it anywhere else. Did it get removed?
