Current Behavior

When generating a new Next.js application or library, using the React 19 RC, and running the default generated test, there's a console warning:

> jest

  console.warn
    Warning: Your app (or one of its dependencies) is using an outdated JSX transform. Update to the modern JSX transform for faster performance: https://react.dev/link/new-jsx-transform

       5 | describe("Page", () => {
       6 |   it("should render successfully", () => {
    >  7 |     const { baseElement } = render(<Page />)
         |                                    ^
       8 |     expect(baseElement).toBeTruthy()
       9 |   })
      10 | })

I cannot figure out where the outdated transform is being specified - babel-jest, the @nx/next/babel preset, or the underlying next babel preset.

Expected Behavior

The new JSX transform should be used during tests
