With the removal of the node view and the coming addition of the tree-view added to all other views, we need to update various images and gifs of AboutCode Manager.

In many places such as https://github.com/nexB/aboutcode-manager/wiki/Creating-Components, the node view is shown even though it no longer exists and most documentation does not mention it.

We probably do not need extensive usage gifs like we had in the past, just updated images.
