Use Prev/Next pagination for exploring projects
This changes the pagination of the "Explore" pages so they use a simpler
pagination system that only shows "Prev" and "Next" buttons. This
removes the need for getting the total number of rows to display, a
process that can easily take up to 2 seconds when browsing through a
large list of projects.
Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/27390
