Update twenty-front commands (#4667)

# This PR

- Moves dev and ci scripts to the `project.json` file in the
twenty-front package
- Adds a project.json file in the root of the project with the main
start command that start both twenty-server and twenty-front
applications concurrently
- Updates the script command of the root project with the start:prod
command (replacing the start command which will be used in dev with the
help of nx)
- Add a start:prod command in the twenty-front app, replacing the start
command (now used for dev purpose)

Issue ref #4645
