Improving the installation process of the magento Cloud template

[guvra]

Hi,

The installation process of this cloud template has multiple pain points compared to community/enterprise edition.
As a consequence, it is quite complex to maintain a dev tool chain that automates the creation of a Magento project.

Here are the main issues:

1. This repository is not hosted on packagist:

   • Initializing a Magento community/enterprise project: composer create-project.
   • Initializing a Magento cloud project: git clone -b 2.4.4 --depth 1 git@github.com:magento/magento-cloud.git .

2. In composer.json, the require-dev section is missing. So in our boilerplate, we have to create a temporary Magento enterprise project (with --no-install option), get the dev packages list with composer show -s (involves using sed and grep to filter the output...), and add them to the Magento cloud project with composer require...

   It's standard practice to include dev packages by default. On a production environment, you are supposed to run composer with the --no-dev option.

3. The autoload-dev section is not up to date. The following entry is missing:

   "autoload-dev": {
       "psr-4": {
           "Magento\\PhpStan\\": "dev/tests/static/framework/Magento/PhpStan/"
       }
   }

   This missing entry cannot be added with the composer command-line, so the only way to add this missing entry is to edit the file manually.

edit: I would also suggest the following improvements:

• Removing the composer.lock file from this repository.
• Settting the min stability to "stable".
