chore: Leave comments about not refactoring pagination tests (#1121)

Relates to #963 

We decided to deprioritize refactoring the pagination tests since we do
not anticipate needing updates soon. This PR adds a comment to the two
pagination related test files indicating that future devs should follow
the page object model instead.
