chore(rspack): add jest babel config to e2e

[mandarini]

Adding this extra jest config to the child project generated by the e2e test is the only way to make the nx ecosystem ci tests pass. If this is not added, then when the e2e test tries to test the generated project, it throws a jest error:

          /home/runner/work/nx-ecosystem-ci/nx-ecosystem-ci/workspace/nx-rspack/nx-labs/tmp/nx-e2e/proj/src/app/app.spec.tsx:3
          import { render } from '@testing-library/react';
          ^^^^^^
          SyntaxError: Cannot use import statement outside a module
