Feature/migrate to vite

Migrate to vite

The purpose of this feature is to use vite instead of create-react-app.

Changes introduced with Vite

• The entry point is now at ./index.html instead of public/index.html
• No need of %PUBLIC_URL%
• Use of alias path to access files. @/utils/urls refers to ./src/utils/urls.js for example
• Files with JSX must be in .tsx or .jsx format
• Remove legacy webpack auto compiled module, like plugins for Paella. Use of @cern-vc/cern-paella-plugins instead.
