React-Script Upgrade - Registration Repo

[jjeroch]

Summary

Upgrade portal-registration to new react-script

Details

For react-scripts 5.0.1 no new versions are provided since two years https://www.npmjs.com/package/react-scripts

This is a high maintenance and security issues as portal frontend and registration app are heavily reliant on it and library has lots of dependencies.
