Title: Quick accessibility fixes

Feedback from an accessibility review showed misuse of the `nav` tag was making the document difficult to read:

`nav` tags were removed from the footer as being in the footer tag gave enough context.
Skip links didn't need `nav` tags.
The breadcrumb was better suited to being identified by a breadcrumbs ARIA role.
