Add compatibility with symfony/process 8.0

[Basster]

With the release of symfony 8, we can hopefully rely on symfony/process 8.x

The errors on the ci are the same as before. https://github.com/php-webdriver/php-webdriver/actions/runs/19982221867

symfony/process 8 installation is covered here https://github.com/php-webdriver/php-webdriver/actions/runs/19743236523/job/56571964000?pr=1134#step:4:72

In my point of view, the failing tests should be handled in seperated PRs.

Hi, thanks and sorry for waiting, this has been done and merged in #1142, I updated also other dependencies.

I will do few other minor housekeeping updates and release a new version of the library soon.
