In symfony#58865, the version constraint for `doctrine/data-persistence` was updated for the root and doctrine bridge. The change in the root `composer.json` was lost in the merge of 7.1 in 7.2.

- [6.4 merged in 7.1](symfony@39b5b8f) ✅
- [7.1 merged in 7.2](symfony@e2f2a96) ❌

This is a **minor change**, as it does not change the constraints of `symfony/doctrine-bridge`. But it's necessary to run tests with the latest package versions.
