Adding support of symfony/process ^7.0

[elpoutro]

I want support for symfony/process ^7.0 to be able to use php-ansible on Symfony7.0.

I have tested with PHP8.1, 8.2, and 8.3:

1. with PHP8.1:

composer update set symfony/process to v.6.4.7
phpunit stay OK (73 tests, 140 assertions)

2. with PHP8.2:

composer update set symfony/process to v.7.0.7
phpunit stay OK (73 tests, 140 assertions)

3. with PHP8.3:

composer update set symfony/process to v.7.0.7
I get this error:

1) Asm\Ansible\Command\AnsibleGalaxyTest::testExecute
Symfony\Component\Process\Exception\RuntimeException: Unable to launch a new process.

But i get the same error with current php-ansible version (how use symfony/process to v.6.4.7). So i think we can path through the php 8.3 compatibility for this merge request?

Not that i try to fix quickly the php8.3 issue but i didn't understood the problem. I wonder if i miss a php8.3-* package on my system... Is anybody can make the same test to check this possibility?

I m closing because #93 do it better than i suggested.
