Add ‘complex header’ example to review app

[querkmachine]

Mulling over a full-page example that shows the Service navigation component in-situ with the GOV.UK header, phase banner, and other elements that usually appear at the top of a page.

Changes

• Add 'Companies you follow (service navigation with service name)' full-page example, based on part of the Companies House WebFiling service. This example demonstrates:
  • The Service navigation component, with navigation links and service name/URL included.
  • The full-width border variant of the GOV.UK header component.
  • How the GOV.UK header, Service navigation, Phase banner, and Back link/Breadcrumbs components are placed relative to one another.
• Add 'Companies you follow (service navigation with slots)' full-page example. This one additionally demonstrates:
  • The use of slots within the Service navigation component.
  • How the HTML elements and landmarks differ when the service name is not included in the Service navigation component.
• Updates other examples that included navigation within the GOV.UK header component to either remove the navigation, or to move it to within the Service navigation component.

Looks good to me, I guess it will pull through the changes from #5278 when we merge it
