Update to Symfony 7.0

Symfony 7 requires PHP 8.2, so postponing for now on 📌 [11.x] [PP-1] Add PHP 8.3 requirement to Drupal 11.0.x Postponed

Running into lots of "Deprecated NULL placeholder value for key (%name) in: "%name: this field cannot hold more than @count values.". This will throw a PHP error in drupal:11.0.0."

See #3054535-37: Discuss whether to decouple from Symfony Validator →

Pushed a single commit from 🐛 FieldItemList::getConstraints() incorrectly sets $maxMessage as TranslatableMarkup Active which might be enough to get tests passing here.

Second attempt where we only translate messages if we need to; in the case of NULL we use the default validation message.

Happy with doing [#/3431200] separately and after this lands, updating will make 11.x a much better testing target for contrib.

Committed a65bbd5 and pushed to 11.x. Thanks!
