Update to 'symfony/yaml ^6'

[zeravcic]

Is it possible to update the symfony packages dependencies to version ^6?

Laravel 9.x is required!

Reason

Conflict with orchestra/testbench package.

The composer.json file:

    "require-dev": {
        "phpunit/phpunit": "^9.5",
        "phing/phing": "3.*"
    },

Conflict

CLI input:

$ composer require --dev orchestra/testbench:^7

CLI output:

  Problem 1
    - orchestra/testbench[v7.0.0, ..., 7.x-dev] require symfony/yaml ^6.0 -> found symfony/yaml[v6.0.0-BETA1, ..., 6.2.x-dev] but these were not loaded, likely because it conflicts with another require.
    - Root composer.json requires orchestra/testbench ^7 -> satisfiable by orchestra/testbench[v7.0.0, ..., 7.x-dev].

Any help is appreciated! :)
