Solve sf 7 deprecation

[VincentLanglet]

Hi,

I tried this lib with SF7 and got a deprecation,

The "Symfony\Component\HttpKernel\DependencyInjection\Extension" class is considered internal since Symfony 7.1, to be deprecated in 8.1; use Symfony\Component\DependencyInjection\Extension\Extension instead. It may change without further notice. You should not use it from "Shivas\VersioningBundle\DependencyInjection\ShivasVersioningExtension".

This PR solve it, and since the file exist in 5.4 versions, it will still be compatible with every SF 7 versions.

Closes #96
