Fixes coding standards issues

I have tested MR 5. There is still some of error pending.

Thanks!!

The \Drupal call in the Cron class is documented as required. Tests are needed before to correct it.

\Drupal call removed, local tests succeeded.

Please excuse me, the result of this test is incorrect. However, it is possible that the error 'Unsafe usage of new static' may appear, which is why I am proposing a configuration with phpstan.neon.

Thank you all!
