At the moment, if you run any test, you will be hit with this deprecation message, even if the test passes:
$ docker compose exec api vendor/bin/phpunit --filter PublicWikiControllerTest PHPUnit 10.5.63 by Sebastian Bergmann and contributors. Runtime: PHP 8.2.31 Configuration: /var/www/html/phpunit.xml D 1 / 1 (100%) Time: 00:00.070, Memory: 36.00 MB OK, but there were issues! Tests: 1, Assertions: 2, PHPUnit Deprecations: 6.
This command can be used to get the actual message behind those notices

The 6 deprecations are all PHPUnit deprecations from one file tests/Helper/ProfileValidatorTest.php. And the message shows: “Providing invalid named argument ... is deprecated and will not be supported in PHPUnit 11.0.” even though we are still on phpunit^10.5
It seems like they are warning us before we accidentally update to phpunit 11 and break out test suite.
