Make it more clear which environment variables are overwritten #547
Description
Over the last years I did see a lot of people run into issue that symfony serve overwrites the DATABASE_URL depending on the things configured in the docker compose file.
I think It would be great to output the overwrites when starting the symfony serve or server:start webserver.
Currently we have the following output where we could also add a Info boxor inside the green box more information:
[WARNING] The local web server is optimized for local development and MUST never be used in a production setup.
[OK] Web server listening
The Web server is using PHP FPM 8.1.31
https://127.0.0.1:8000

[Info] Docker Integration Environment Variables
DATABASE_URL=....
KAFA_...=....
Currently the behaviour is only documented in https://symfony.com/doc/current/setup/symfony_server.html#docker-integration but sure most don't stumble over it and its unclear for endusers why there .env or .env.local ENVs aren't used.
