Visual regression: pagination on search results page

The last gitlab/ui update changed the appearance of the pager on the search results page: https://new.docs.gitlab.com/search/?q=documentation&page=1

It looks a little off compared to how it looks in Pajamas here: https://gitlab-org.gitlab.io/gitlab-ui/?path=/docs/base-pagination--docs

We need to adjust the CSS here to make it look more like the one in Pajamas. Maybe we have some classes that are overriding these default styles.

This same bug is likely on the Nanoc site as well, we'll also want to clean that up.
