test(node): Ensure logs are auto-printed when a test fails

[mydea]

We can opt-in to show sub process logs in node-integration-tests with DEBUG=1. This PR adjusts this so that we automatically show logs when a test fails. For example, in addition to this:

 FAIL  suites/express/tracing/test.ts > express tracing > should create and send transactions for Express routes and spans for middlewares. xxxx [esm]
 FAIL  suites/express/tracing/test.ts > express tracing > should create and send transactions for Express routes and spans for middlewares. xxxx [cjs]
Error: Timed out waiting for server port
 ❯ waitFor utils/runner/createRunner.ts:648:13
    646|     remaining -= 100;
    647|     if (remaining < 0) {
    648|       throw new Error(message);
       |             ^
    649|     }
    650|   }
 ❯ Object.makeRequest utils/runner/createRunner.ts:533:13

You may see:

stdout | suites/express/tracing/test.ts > express tracing > should create and send transactions for Express routes and spans for middlewares. xxxx [esm]

Node.js v20.19.5
--- End of captured child process output ---

Which should hopefully make it easier to figure out some test failures etc.

brilliant move.

Would be amazing if we could port this to the other runner.ts we have. I think node-core, bun and cloudflare

we can look at this in a follow up I'd say!
