Is your feature request related to a problem? Please describe.

Currently it's not possible to instrument a Node.js application that uses ESM, or to create a custom auto-instrumentation image with asynchronous initialisation logic, because the --require flag injected in the NODE_OPTIONS environment variable doesn't support these use cases.

Describe the solution you'd like

Adding a new useImport or similar flag to the Node.js auto-instrumentation that injects --import /otel-auto-instrumentation-nodejs/autoinstrumentation.mjs instead of --require /otel-auto-instrumentation-nodejs/autoinstrumentation.js, and adding the new file to the provided image that delegates to autoinstrumentation.js but also registers hooks for ESM instrumentation.

Describe alternatives you've considered

I'd be happy to work on this.
