[explorer] Remove extra pagination

Summary:
All the tables have some extra, non-functioning pagination numbers showing at the bottom.
Happened with the datatables version update it seems like, the newer version defaults to showing pagination
but since we are using a custom solution here, need to hide it

Test Plan: preview the site and check those extra pagination numbers arent showing above the actual pagination
