fix pagination.html error

[IcingTomato]

When I am using pagination, there is a 404 Not Found occur.

According to the Pagination-JekyllCN Docs ,

<div class="pagination">
  {% if paginator.previous_page %}
    <a href="/page{{ paginator.previous_page }}" class="previous">Previous</a>
  {% else %}
    <span class="previous">Previous</span>
  {% endif %}
  <span class="page_number ">Page: {{ paginator.page }} of {{ paginator.total_pages }}</span>
  {% if paginator.next_page %}
    <a href="/page{{ paginator.next_page }}" class="next">Next</a>
  {% else %}
    <span class="next ">Next</span>
  {% endif %}
</div>

<a href="/page{{ paginator.next_page }}" class="next">Next</a> is the correct setting.

After changing the pagination.html and _config.yml, the Next Page can work properly.
