Migrate to Next.js

I would like this project to be converted into the Next.js.
create-react-app is causing security issues :

`Dependabot cannot update nth-check to a non-vulnerable version`
The latest possible version that can be installed is 1.0.2 because of the following conflicting dependencies:
```bash
react-scripts@5.0.1 requires nth-check@^1.0.2 via a transitive dependency on css-select@2.1.0
```
No patched version available for nth-check
The earliest fixed version is 2.0.1.
