Remove AddOverrideAttributeToOverriddenMethodsRector from PHP 8.3 and polyfill sets

[TomasVotruba]

The rule adds #[Override] to every single overridden method. In practice that spams the codebase with attributes without bringing real value, so it should not run automatically as part of withPhpSets().

 class SomeChild extends SomeParent
 {
-    #[\Override]
     public function run()
     {
     }
 }

Changes:

• removed from config/set/php83.php
• removed from config/set/php-polyfills.php
• dropped RelatedPolyfillInterface from the rule, as RegisterRelatedPolyfillRectorRule (PHPStan) requires every polyfill-related rule to be registered in the polyfill set

The rule itself stays and can be registered explicitly:

$rectorConfig->rule(AddOverrideAttributeToOverriddenMethodsRector::class);
