Do not run compile-production-assets if we're running a predictive pipeline which does not run E2E tests
This is a follow up from #443498 (comment 1809601010) where we found that this job can take longer to run than the tests we're running, and none of the tests beside E2E tests are depending on this, and we don't run E2E tests in a predictive pipeline: #442943 (closed) so there's little point to run them under such context.
