Replace Lcobucci\Clock\Clock typehints with Psr\Clock\ClockInterface

[Slamdunk]

Parameter #1 $clock of method PSR7Sessions\Storageless\Http\Configuration::withClock() expects Lcobucci\Clock\Clock, Psr\Clock\ClockInterface given.

I checked this briefly: can't change the Configuration without a major release (which we can do).

I'd say that it's a good idea to do so, though.

Also, perhaps we should stop relying on Configuration at runtime, and extract relevant Configuration values in named constructors, so:

    public function __construct(
        private Configuration $config,
    ) {
    }

becomes

    public function __construct(
        private ClockInterface $clock,
    ) {
    }

    public static function fromConfiguration(Configuration $config) : self { ... }
