Minimal PHP Code Causing Issue

Reproduced on PHP 8.4:

https://getrector.com/demo/b1c3546d-96ff-43c0-8182-c58093d6ddb1

Given the following code:

final class DemoFile
{
    protected final $x = true;
}

which valid on PHP 8.4 https://3v4l.org/gXaQt#v8.4.25

changed to:

 final class DemoFile
 {
-    protected final $x = true;
+    final private $x = true;
 }

and cause error:

Fatal error: Property cannot be both final and private

Ref https://3v4l.org/lhT8c#v8.4.25

Expected Behaviour

The final should be removed on private modifier, so should be:

 final class DemoFile
 {
-    protected final $x = true;
+    private $x = true;
 }

I created PR

• [Privatization] Remove final flag on Privatize*Rector from protected to private rector-src#8509

for it.
