Revert "[ci] use --output-logs=new-only to only list tests that changed" (#10584)

Reverts vercel/vercel#10570

This was causing a bug because my assumption about turbo cache hit/miss was incorrect. 

I thought `turbo run test-e2e --listTests` would be use the same cache as `turbo run test-e2e` but it does not. So what was happening is that tests were not running on a second push to a PR because turbo already "cached" the result of `--listTests` so that `new-only` was saying there are no new tests and nothing to run 🤦
