[deprecation] Deprecate AddParamArrayDocblockBasedOnArrayMapRector

[TomasVotruba]

The rule looks for one array_map() call inside a method body, reads the param type of its closure, and writes that as a @param docblock for the whole parameter.

One call site is not evidence about the parameter. The closure only tells us what that single array_map() reads; callers may pass anything else the native array type allows.

 final class SomeClass
 {
+    /**
+     * @param string[] $names
+     */
     public function run(array $names): void
     {
         $names = array_map(fn(string $name) => trim($name), $names);
     }
 }

If any caller passes Name[], or the closure param type is itself just a guess, the docblock is wrong - and PHPStan trusts it over the native array.

Add the docblock manually, or write a custom rule that knows the project's call sites.

Changes:

• rule implements DeprecatedInterface and throws on refactor()
• removed from the TypeDeclarationDocblocksLevel set
• test case + fixtures removed
• ArrayMapClosureExprFinder removed, it had no other user
