ci(workflow): use release build of next-dev for integration test (#3650)
Context: https://vercel.slack.com/archives/C04KC8A53T7/p1675471724960239?thread_ts=1675469142.533699&cid=C04KC8A53T7
There are some expected failures with debug build (without proper setup) for the integration test. This PR choose to build release binary, as it'll also help overall test turnaround time since debug build is lot slower.
