Adjust config directory logic check on config import script

[duncancm9]

The config directory can be in different paths and not necessarily in the path defined here:

This can cause config to not be imported when desired.

The point of the logic is to make sure the drush cim command isn't run on Drupal 7 sites. I think I have some logic I've added recently to help with this. Use drush eval or drush status to get the drupal version. See for an code check using the VERSION constant. https://github.com/fourkitchens/evercurrent-v2/blob/main/web/modules/custom/evercurrent_server/src/DrushCommand/PhpEval/ProjectUpdates.php#L2-L23
