fix: correct package.json exports for mfRuntimePlugins in modern-js package

- Fixed incorrect 'require' paths pointing to ESM instead of CJS files for:
  - shared-strategy module
  - resolve-entry-ipv4 module
  - inject-node-fetch module
- This resolves MODULE_NOT_FOUND errors in modern-js-plugin tests
- All exports now correctly point to their respective ESM/CJS builds

Fixes failing CI test: modern-js-plugin › patchMFConfig tests
