Thanks for the PR 😍

How to test these changes in your application

1. Define the SYMFONY_ENDPOINT environment variable:

   # On Unix-like (BSD, Linux and macOS)
   export SYMFONY_ENDPOINT=https://raw.githubusercontent.com/symfony/recipes-contrib/flex/pull-1673/index.json
   # On Windows
   SET SYMFONY_ENDPOINT=https://raw.githubusercontent.com/symfony/recipes-contrib/flex/pull-1673/index.json

2. Install the package(s) related to this recipe:

   composer req 'symfony/flex:^1.16'
   composer req 'shopware/app-bundle:^4.0'

3. Don't forget to unset the SYMFONY_ENDPOINT environment variable when done:

   # On Unix-like (BSD, Linux and macOS)
   unset SYMFONY_ENDPOINT
   # On Windows
   SET SYMFONY_ENDPOINT=

Whats the best way here? I made doctrine optional as we support dynamodb in that bundle now too. So the new require flow is like: composer require shopware/app-bundle doctrine/orm symfony/doctrine-bridge

I make the default in-memory, so it does not require anything

Now it's fine, we don't support Symfony 5
