Fixes #1782

Screenshot

In order to see how the pagination functions, I temporarily set the # items per page to 10 https://github.com/CDCgov/phdi/assets/40042932/9455067a-d450-4b01-81b0-0ebdd1b90209

With items per page set to 25 (since there are < 25 items total, this is what the single page looks like)
