curious, why do you need a JSON machine format .. compared to current PHP machine format (.env.local.php)

perhaps the dotenv:dump command should be tweaked instead

To read information from external projects without changing them.

For my understanding, dotenv:dump writes files to a .env.local.php inside the project directory which is not always desired.

In my case, I want to get information from a project configuration without changing the project as I'm not in charge for the project.

A machine-readable output in DebugCommand allows me to get information from any symfony project without needing to check if there is an .env file or .env.local.php (or something else) from outside.

Other debug:* commands use the DescriptorInterface. Adding a new output format is a great opportunity to refactor and use this feature.

By the way, we need tests for this feature.

Closing for now as it should leverage the already existing infrastructure, which would make a very different PR.
