Since symfony#60394 using `add()` is deprecated. This means that our tests can trigger deprecations on older branches when the high deps job is run. This usually is not an issue as we silence them with the `SYMFONY_DEPRECATIONS_HELPER` env var. However, phpt tests are run in a child process where the deprecation error handler of the PHPUnit bridge doesn't step in. Thus, for them deprecations are not silenced leading to failures.

We did something similar before in symfony#60376.
