Bump version of symfony/options-resolver

[SebastienGautier]

The library currently restrict the version 6 of symfony/options-resolver making it impossible to upgrade to Symfony 6. The changelog states "no significant changes" for all versions so no breaking change seems to be expected. I tried upgrading locally and I had to upgrade friendsofphp/php-cs-fixer to version 3 as well. All the test results are the same.

What do you think ?
