Scrollspy documentation regarding anchor class

The Scrollspy documentation has a list of requirements to "activate" the feature. One requirement that appears to be missing is the presence of class="nav-link" in all anchor tags in your nav component. I think this is important to mention, as it took quite a bit of trial and error to discover this while trying to enable scrollspy on an auto-generated nav component.
