Suggestion: Option to load a different .env file

[ThomasLandauer]

My use case: My app uses the Symfony HTTP Client, which throws a TransportException if it can't connect: https://symfony.com/doc/current/http_client.html#handling-exceptions
And I want to assert that my app catches it correctly. So my idea: Put some bogus URL in .env.test-failing, then load it in framework.php:

'base_uri' => '%env(string:URL)%'

So something like $I->loadEnvFile('/.env.test-failing') would be great! And if that's not possible, maybe a CLI parameter --env-file=.env.test-failing?
