Add additional verification step for Updating your project with changes from a git repository procedure

Description of problem:

Current documentation notes "

• You can view the changes pulled from the remote repository in your local repository. Immediately after pulling the latest changes, in the lower-right corner of the JupyterLab interface, click DETAILS."

However the DETAILS option is just a short notification that appears in the lower right-hand corner of the screen when pull changes from Git. If a user doesn't see the brief pop-up, they may not know how to see changes. Instead of looking a the brief pop-up notification, they could look at the history in the Git extension window.

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

Steps to Reproduce

1. In the JupyterLab interface, click the Git button
2. Click the Pull latest changes button
3. Immediately after pulling the latest changes, in the lower-right corner of the JupyterLab interface, click DETAILS.

Actual results:

Expected results:

Allow a user to easily see changes made to Git repository

Reproducibility (Always/Intermittent/Only Once):

Always

Build Details:

Red Hat OpenShift Data Science operator version 1.0.14.
