Turbopack: fix instrumentationClientInject with type:module (#94184)

generated by Turbopack at `[project]/__next_instrumentation_client.js`
would get treated as ESM. But it always contains CJS, causing
```
Uncaught (in promise) ReferenceError: module is not defined
at module evaluation (__next_instrumentation_client.js:3:1)
```
