file_validate_extensions() removed in D11

removed deprecated function replaced with file,validator service

With this patch I'm getting

TypeError: Drupal\google_analytics_reports_api\Form\GoogleAnalyticsReportsApiAdminSettingsForm::__construct(): Argument #6 ($file_validator) must be of type Drupal\file\FileValidatorInterface, Drupal\file\Validation\FileValidator given

Changing the use from
use Drupal\file\FileValidatorInterface;
to
use Drupal\file\Validation\FileValidatorInterface;

fixes the error.

Fix attached for D11

legitimate needed change.
Please, create an MR to merge it directly.

When this problem triggers an error, it doesn't seem to pass on the field name to the logger. This then results in another error: 🐛 TypeError: Drupal\Component\Utility\Html::escape(): Argument #1 ($text) must be of type string, null given Needs review
