Support ECMAScript Modules in examples and create-supertokens-app

[gopi-chand-reddy]

🚀 Feature

ESM is natively supported by modern JavaScript engines and browsers. If SuperTokens moves away from CJS to ESM, we can migrate our React projects from react-scripts to more modern tools like vite.

We migrated our project to vite with the help of viject. We had to manually replace require("reactRouterDom") with import * as reactRouterDom from "reactRouterDom".

Implementation details

1. Modify create-supertokens-app to use vite instead of react-scripts.
2. Ensure all the examples use ESM (import and import()) and not CJS (require and require())
