Collector::__wakeup is deprecated

[ro0NL]

Hi,

It seems a deprecation was missed solving in the collector:

Since symfony/http-kernel 7.4: Implementing "Http\HttplugBundle\Collector\Collector::__wakeup()" is deprecated, use "__unserialize()" instead.

do you want to do a pull request to add __unserialize ? i wonder if we can simply remove __wakeup or if that is still needed for old versions of symfony?
