Ignore phpunit deprecations already ignored by Core

I can also confirm seeing these deprecation messages in current build pipelines, see:
https://git.drupalcode.org/issue/admin_toolbar-3532958/-/jobs/5862610#L129

    1 test triggered 1 deprecation:
    
    1) /builds/issue/admin_toolbar-3532958/vendor/symfony/deprecation-contracts/function.php:25
    Since symfony/validator 7.3: Passing an array of options to configure the "Drupal\Core\Validation\Plugin\Validation\Constraint\NotNullConstraint" constraint is deprecated, use named arguments instead.
    
    Triggered by:
    
    * Drupal\Tests\admin_toolbar_search\FunctionalJavascript\AdminToolbarToolsSearchTest::testToolbarSearch (34 times)
      /builds/issue/admin_toolbar-3532958/admin_toolbar_search/tests/src/FunctionalJavascript/AdminToolbarToolsSearchTest.php:112
    

 
Would you have any advice on how these deprecation warnings could be addressed?

The error message is not very clear: would there be any code changes expected on our end?
See the line of code reported above:
https://git.drupalcode.org/issue/admin_toolbar-3532958/-/blob/3532958-35...

What should we change to fix these warnings in the code reported as deprecated?

Any pointers, related issues or recommendations would be greatly appreciated.
Thanks in advance!

I've configured it to just have deprecations we have in experience_builder.
I've also disabled the fail on deprecations with:
- SYMFONY_DEPRECATIONS_HELPER= "disabled&ignoreFile=$DRUPAL_PROJECT_FOLDER/.phpunit-deprecation-ignore.txt" (see more)
- PHPUNIT_FAIL_ON_PHPUNIT_DEPRECATION=0: (see more)

But the job is still failing. Any idea?

I've set

SYMFONY_DEPRECATIONS_HELPER=max[total]=99999

and it doesn't work either.
