Missing step when importing an existing notebook file from a git repository using a notebook cell

Description of problem:

For documentation module: Import an existing notebook file from a Git repository using the command line interface [procedure]

After step 4, there needs to be a step that tells the data scientist to "run" the cell otherwise the  Git repository will not be cloned.

Prerequisites (if any, like setup, operators/versions):

Steps to Reproduce

1. Copy the HTTPS URL for the Git repository.
2. Open your notebook in JupyterHub.
3. Add a cell to the notebook.
4. Enter ! followed by the git clone command.
