Last breadcrumb should not be a link on non-repo pages

Created by: tjkandala

When the breadcrumb element is a link, it renders as a link regardless of its depth.

The deepest breadcrumb should be rendered as plain text even when it is a link.

The current behavior should be maintained for repo pages.

Note: Make sure that consumers of the Breadcrumbs API do not need to be aware of this logic as a result of the solution.
