Twig 2.x deprecated tokenizing via a string source

[DiegoPino]

What is this?

🚀 @giancarlobi found a deprecated (changed) signature method in our Twig template validation when running a 2.x Twig on Drupal 9.0.4. here https://github.com/esmero/format_strawberryfield/blob/master/src/Plugin/Validation/Constraint/TwigTemplateConstraintValidator.php#L47

Fix is to convert the source into the proper Object before ::tokenizing
Its documented here https://twig.symfony.com/doc/2.x/deprecated.html as deprecated but of course Drupal 9 was not "telling" us that..

Fix coming!

Fix was added to #92. Its a blind fix in the sense that i could not test it because computer froze and crashed (dump computer). So @giancarlobi please test whenever you can. Thanks a lot
