Allow users to configure the URL for "Home" in breadcrumbs

[adamjohnson]

We see this accessibility error in local development on every single site we make. The "Home" href in the main nav is different from the "Home" href in the breadcrumbs. For example, one is:

• https://launchlab.wvu.edu/home
• and the other is:
• #home

I would like to be able to customize the content of the href attribute in the r:breadcrumbs tag. I think this will help CleanSlate designers when remediating their sites. People like to be able to achieve a "clean slate" in local development (see what I did there?).

I believe you can already do this by adding a breadcrumbs data point in mock_data.yml

breadcrumbs: |
  <ul class="wvu-breadcrumbs__crumbs">
    <li><a href="/">Home</a></li>
    <li class="active">Page</li>
  </ul>

By doing this however you lose the interpolation of attribute options from the radius tag.
