[Sets] Drop Symfony per-version set providers from the collector

[TomasVotruba]

Companion to rectorphp/rector-symfony#1010.

Symfony3SetProvider … Symfony8SetProvider registered 208 per-version ComposerTriggeredSets. Every rule in them is already in config/sets/symfony/composer-based.php, where it carries its own package version constraint — verified rule by rule in that PR, 0 rules missing. rector-symfony removes those providers, so the collector stops asking them for sets.

SymfonySetProvider goes with them, in the same rector-symfony PR: the composer-based set is reachable through SymfonySetList::COMPOSER_BASED, which is exactly what withComposerBased(symfony: true) adds, and the remaining Symfony sets through their own SymfonySetList constants.

 use Rector\Set\SetProvider\PHPSetProvider;
-use Rector\Symfony\Set\SetProvider\Symfony3SetProvider;
-use Rector\Symfony\Set\SetProvider\Symfony4SetProvider;
-use Rector\Symfony\Set\SetProvider\Symfony5SetProvider;
-use Rector\Symfony\Set\SetProvider\Symfony6SetProvider;
-use Rector\Symfony\Set\SetProvider\Symfony7SetProvider;
-use Rector\Symfony\Set\SetProvider\Symfony8SetProvider;
-use Rector\Symfony\Set\SetProvider\SymfonySetProvider;
 use Rector\Symfony\Set\SetProvider\TwigSetProvider;

         $setProviders = [
             new PHPSetProvider(),
             new CoreSetProvider(),
             new PHPUnitSetProvider(),
-            new SymfonySetProvider(),
-            new Symfony3SetProvider(),
-            new Symfony4SetProvider(),
-            new Symfony5SetProvider(),
-            new Symfony6SetProvider(),
-            new Symfony7SetProvider(),
-            new Symfony8SetProvider(),
             new DoctrineSetProvider(),
             new TwigSetProvider(),
         ];

TwigSetProvider stays — SetGroup::TWIG is wired into withComposerBased(), so its composer-based trigger is still resolved through SetManager.

Follow-up, not in this PR

rector-symfony#1010 also trims TwigSetProvider to its single composer-based trigger. Once that is released and pulled in here, SetManagerTest needs updating — testMatchComposerTriggered() asserts 8 Twig triggered sets, and provideInstalledTwigData() expects the per-version Twig sets alongside the composer-based one.

CI unrelated to sets, caused by PHPStan type change.
