Description: 

Drupal 10 was updated to Symfony 5.4 as a stepping stone to Symfony 6. The change will be released with alpha1 as an interim step to help contributed projects update to Symfony 6. While direct Symfony API use is not common in Drupal projects, this interim step was introduced to help those who use Symfony APIs directly to be able to check for deprecated APIs in two steps. Since Symfony 4 does not have all deprecated APIs defined for Symfony 6, this interim step could help identify code changes required.
