Injecting php version of the default interpreter from PHPSTorm's project setting

[popnikos]

Describe the need of your request

With PHPStorm, the plugin does not provide context of the specific php / phpunit versions used into a project.
The chat answers may contains code with unexisting method for a specific project, and can make tests not running because the version of phpunit is not detected.

Proposed solution

Add an option to specify php version from project setting while starting a new chat .
also add an option to specify phpunit version from project settings.

At least, add a template variable such as settings.php.language_level or settings.Test Frameworks.PHPunit.version (not sure this informations are available or f names are those ones.
Also take options from remote interpreter.

Additional context

This will help code suggestions and autocomplete to be reliable with current project settings.
