[React Course] Use vite instead of create-react-app for starting a new project

[SarahSchmid]

I don't think I have to go deep into the why. Create-react-app in no longer maintained and got removed from the official React docs in march 2023. I would recommend to use Vite instead of CRA in the React course due to its similarity and to keep the simplicity of starting a new React project.
