bug: Service worker registration not working in react

[satheshsat]

Bug Report

Ionic version:
[x] 5.x

Current behavior:
Try to register service worker file ( service-worker.js ) from root path. But there is no such a file in build.

Expected behavior:
Need to register service worker for PWA

Steps to reproduce:
ionic start pwa blank --type=react
change serviceWorker.unregister(); to serviceWorker.register(); in index.tsx
ionic build --prod
npx serve build
Service worker can't be registered in local. But it runs service worker validation.
console: GET http://localhost:5000/service-worker.js 404 (Not Found)

Thanks for the issue. There were some changes in how react-scripts v4 generated PWA-related files that caused this to no longer work. We have updated our starters to properly generate the service worker file now.
