Drupal calls should be avoided in classes, use dependency injection instead

I have reviewed this issue. The phpcs coding standards stand fixed now. There are few additional warnings also fixed in this.

phpcs --standard=DrupalPractice  --extensions=php,module,inc,install gin_login/

These all has been fixed.

There are still phpcs issues, see https://git.drupalcode.org/issue/gin_login-3427099/-/jobs/1065196

I've fixed the phpcs errors and merged this. Thanks!
