Update crane.unl.edu to crane-ood.unl.edu in docs
The screenshots should be updated to use crane-ood.unl.edu instead, https://hcc.unl.edu/docs/applications/app_specific/jupyter/. Also, the link to Crane (https://hcc.unl.edu/docs/applications/app_specific/jupyter/crane.unl.edu) is broken in the web page.
