Example 2: bootstrap Breadcrumb Accessibility

Since breadcrumbs provide a navigation, it’s a good idea to add a meaningful 
label such as aria-label="breadcrumb" to describe the type of navigation
provided in the <nav> element, as well as applying an aria-current="page"
to the last item of the set to indicate that it represents the current page.
