Feature Request

As mention in #8140 it would be great to configure the phpstan extension from the rector.php file and not have additonal phpstan or change the own phpstan configuration for it.

Diff

-    $rectorConfig->phpstanConfig(__DIR__ . '/phpstan.neon');
+    $rectorConfig->phpstanConfigs([
+        '__DIR__ . '/phpstan.neon',
+        '__DIR__ . '/vendor/phpstan/phpstan-doctrine/extension.neon',
+        '__DIR__ . '/vendor/phpstan/phpstan-symfony/extension.neon',
+    ]);

I think it would make sense then deprecate phpstanConfig in favor of phpstanConfigs. In cases of rector-symfony, rector-doctrine, ... the docs should be mentioning configuring this. So rector works correctly on symfony services and doctrine entities, ...
