Add support for numbered pagination

[colinrotherham]

This PR adds support for numbered pagination from NHS.UK frontend v10.1.0

To differentiate between pagination links (top level) versus pagination list items, this is a breaking change:

  <Pagination>
-   <Pagination.Link href="/section/treatments" previous>
-     Treatments
-   </Pagination.Link>
-   <Pagination.Link href="/section/symptoms" next>
-     Symptoms
-   </Pagination.Link>
+   <Pagination.Item labelText="Treatments" href="/section/treatments" previous />
+   <Pagination.Item labelText="Symptoms" href="/section/symptoms" next />
  </Pagination>

Which now means both types of pagination are supported:

Pagination (default)

<Pagination>
  <Pagination.Item href="/section/treatments" labelText="Treatments" previous />
  <Pagination.Item href="/section/symptoms" labelText="Symptoms" next />
</Pagination>

Pagination (numbered)

<Pagination>
  <Pagination.Link href="/results?page=1" previous />
  <Pagination.Item href="/results?page=1" number={1} />
  <Pagination.Item href="/results?page=2" number={2} current />
  <Pagination.Item href="/results?page=3" number={3} />
  <Pagination.Link href="/results?page=3" next />
</Pagination>
