Allow Symfony 8

[daFish]

This change allows the installation with Symfony 8. It also installs symfony/var-exporter to be compatible with Doctrine ORM 3.0.

Great work!

@Kreyu Could you review the PR from @daFish ?
You also mentioned you don't have the time to invest on this project anymore. We think this bundle is however very useful (and maybe the only good Datatable implementation in Symfony at all). Are you open for other maintainers on this project?
