[PHPUnit120] Add AnyMatcherToNewAnyInvokedCountRector for deprecated any() matcher assign

[TomasVotruba]

TestCase::any() is soft-deprecated since PHPUnit 12.5, hard-deprecated in 13.0 and removed in 14.0. See sebastianbergmann/phpunit#6461

This rule flips the standalone matcher assign to a direct instance:

 use PHPUnit\Framework\TestCase;

 final class SomeTest extends TestCase
 {
     public function test(): void
     {
-        $matcher = $this->any();
+        $matcher = new \PHPUnit\Framework\MockObject\Rule\AnyInvokedCount();
     }
 }

Scope is deliberately narrow — only an Assign whose right side is a bare $this->any() on a TestCase/Assert. First-class callables, calls with args and non-PHPUnit any() methods are skipped. The expects($this->any()) case is already covered by RemoveExpectAnyFromMockRector.

Registered in the composer-based set, bonded to phpunit/phpunit >=12.5.

Note: AnyInvokedCount is marked @internal upstream. The upstream advice is to restructure the test towards createStub() or a specific matcher, which is out of reach for an automated rewrite, so the direct instance is used as the closest mechanical equivalent.
