Bump dev dependencies, PHPUnit 13

[TomasVotruba]

composer update + vendor/bin/jack raise-to-installed, with PHPUnit taken from 11.5 to 13.

 "require-dev": {
-    "phpunit/phpunit": "^11.5",
+    "phpunit/phpunit": "^13.2",
-    "rector/jack": "^0.5",
+    "rector/jack": "^1.0",
-    "symplify/easy-coding-standard": "^13.1",
+    "symplify/easy-coding-standard": "^13.2",
-    "symplify/phpstan-rules": "^14.10",
+    "symplify/phpstan-rules": "^14.12",
 }

This one is not optional anymore - rector-src now requires sebastian/diff ^9 (rectorphp/rector-src#8220), which PHPUnit 11.5 cannot satisfy, so composer update fails on main as it stands.

One removed attribute took out 47 tests

PrePromotedTest pins a php version below constructor promotion:

$rectorConfig->phpVersion(PhpVersionFeature::TYPED_PROPERTIES);

That was safe because the class ran in its own process. PHPUnit 13 dropped RunClassInSeparateProcess in favour of the plural form, so the attribute silently stopped applying and the pinned version leaked into every test that ran after it - 47 fixtures lost their promoted constructors:

-    public function __construct(private readonly SomeService $someService)
+    private SomeService $someService;
+    public function __construct(SomeService $someService)
     {
+        $this->someService = $someService;
     }

-use PHPUnit\Framework\Attributes\RunClassInSeparateProcess;
+use PHPUnit\Framework\Attributes\RunTestsInSeparateProcesses;

-#[RunClassInSeparateProcess]
+#[RunTestsInSeparateProcesses]

PHPStan catches the removal too - Attribute class PHPUnit\Framework\Attributes\RunClassInSeparateProcess does not exist.
