Which area(s) of Next.js are affected? (leave empty if unsure)

Jest (next/jest)

To Reproduce

1. Install Next.js v13.4.10
2. Follow the standard jest setup: Setting up Jest (with the Rust Compiler)
3. Add backend code in lib/ that uses react-dom/server.
4. Add corresponding jest test.
5. Run jest and observe error NEXT_RSC_ERR_SERVER_IMPORT: react-dom/server

Describe the Bug

It seems next/jest from Next.js 13.4.10 mistakenly treats backend code in lib/ as server component and then uses a jest next/swc transform that forbids import from react-dom. But the fact is that the backend code in lib/ has nothing to do with server component (or client component).

jest gives the following error:

  x NEXT_RSC_ERR_SERVER_IMPORT: react-dom/server
     1 | import { renderToStaticMarkup } from "react-dom/server";
       : ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Note that the error only happens on v13.4.10 and reverting back to v13.4.9 dismisses it. Thus it might be caused by one of the following PRs based on the release note of v13.4.10:

• fix(next/jest): jest can not load server-only code: fix(next/jest): jest can not load server-only code #52393
• feat(next-swc): report native bindings load err code: feat(next-swc): report native bindings load err code #52570
• feat(turbopack): support swc transform plugins : feat(turbopack): support swc transform plugins  #50401

Expected Behavior

There shouldn't be any error. next/jest shouldn't treat any backend code as server component.
