[8.x] Server command: Allow xdebug auto-connect to listener feature

[pionl]

👋

To allow xdebug to auto-connect PHPStorms listener we need to pass env variables from the docker container to the PHP process.

We need to pass 2 ENV VARIABLES:

• PHP_IDE_CONFIG - setups which mapping the PHPStorm will use
• XDEBUG_SESSION - starts the xdebug session

This PR is connected with laravel-sail PR.
