Fix Next.js tests

[bizob2828]

Description

It turns out since Next 15 our getServerSideProps tests are failing but getting swallowed from starting the dev server. Also we had to pin to < 16 for other reasons(next.config.js options that no longer exist). We need to fix the next tests to properly error, then fix the instrumentation and configuration in app for Next 16.
