Add require-in-the-middle to default externals (vercel#70922)

Closes PACK-3288
Closes vercel#70424

Sentry uses `open-telemetry`, which uses `require-in-the-middle` which:
- overrides the global `Module.prototype.require`, even when bundled
- reads `require.cache` which when bundled is Turbopack's registry (not
the outer Node.js one)


Because of this, `require-in-the-middle` is broken/results in a broken
environment when it's bundled (e.g. via `instrumentation.js`).
