[Symfony6] The Drupal\Tests\views\Unit\Plugin\argument_default\QueryParameterTest fails for Symfony 5.4

Problem/Motivation

The Drupal\Tests\views\Unit\Plugin\argument_default\QueryParameterTest fails for Symfony 5.4 with the following deprecation warning:

2x: Since symfony/http-foundation 5.1: Retrieving a non-string value from "Symfony\Component\HttpFoundation\InputBag::get()" is deprecated, and will throw a "Symfony\Component\HttpFoundation\Exception\BadRequestException" exception in Symfony 6.0, use "Symfony\Component\HttpFoundation\InputBag::all($key)" instead.
    2x in QueryParameterTest::testGetArgument from Drupal\Tests\views\Unit\Plugin\argument_default

Proposed resolution

Update the plugin Drupal\views\Plugin\views\argument_default\QueryParameter. When the plugin is fixed you will get the exception BadRequestException. Parameter cannot be a string, they must be of the type array. See: https://github.com/symfony/symfony/blob/5.4/src/Symfony/Component/HttpFo...
