Added DDEV Support

[faytecCD]

Added support for DDEV, which can be used when adding a project.

However, I think the UI should prompt the user on which command to run or let the user select the environment (providing suggestions based on detection).

Running commands directly like this may lead to incorrect dependency versions if a PHP executable other than the expected one is selected.

Additionally, a .node-version file has been added to help identify the Node.js version used by the project (from GitHub Actions).

Also, we might not want to ignore package-lock.json.
