Symfony 8 support

[Jesmaster]

Hi guys, checking in on merging the pull request #651

This is the last package preventing me from updating my project, thanks!

please do not open issues when there are already pull requests. this is open source code, there is no service contract.

if you want to help, please try the #651 branch and e.g. do pull requests against that branch to improve things.
