Autofill the.env file with the "composer --no-interaction" command

Currently, our production is runned without a .env.
All is in the current environment variables.

So in production mode, we do not want to run want to answer to questions, just copy it.

This is an example of the result:
```bash
▶ composer install --no-interaction
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Nothing to install or update

> Companienv\Composer\ScriptHandler::run
It looks like you are missing some configuration (46 variables). I will help you to sort this out.
