sentry-javascript: Incorrect `NEXTJS_REQUEST_ASYNC_STORAGE_MODULE_PATH` in Next.js 13.4.20

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Sentry Saas (sentry.io)

Which SDK are you using?

@sentry/nextjs

SDK Version

7.68.0

Framework Version

13.4.20

Link to Sentry event

No response

SDK Setup

npx @sentry/wizard@latest -i nextjs

Steps to Reproduce

1. Install the Next.js canary release (yarn add next@13.4.20-canary.20) in a project using the Next.js 13 App Directory and Route Handlers.
2. Implement the Sentry plugin in next.config.js.
3. Run next build.
4. Observe a console warning: The Sentry SDK could not access the RequestAsyncStorage module. Certain features may not work. There is nothing you can do to fix this yourself, but future SDK updates may resolve this.
5. Observe an error when building each route handler wrapped by Sentry: Module not found: Can't resolve '@sentry/nextjs/build/esm/config/templates/requestAsyncStorageShim.js'

Expected Result

Next.js should successfully build all Route Handlers wrapped by Sentry

Actual Result

Identified the offending line in packages/nextjs/src/config/loaders/wrappingLoader.ts#L19, which should use next/dist/client/components/request-async-storage.external
