ReadOnlyPropertyRector should not add readonly keyword to class properties which do not have native type in parent

Bug Report

Subject	Details
Rector version	0.12.5

If a class has property without a native type, any child class can't declare the native type. PHP doesn't allow it. Also readonly is not allowed without native type. So Rector should not try to add readonly to child class property.

Minimal PHP Code Causing Issue

<?php

class Foo
{
    /** @var array */
	public $foo;
}

class Bar extends Foo
{
    /** @var array */
	public $foo = ['foo', 'bar'];
}

Expected Behaviour

Rector should not add readonly to foo property in class Bar.

Note: Demo site seems to run on PHP 8.0 still. So I couldn't manage to run the rector there. In any case this is the link: https://getrector.org/demo/1ec51e77-1a28-6c06-9386-1f9089bacc07

Also maybe a separate bug, readonly keyword should not be added if the property has a default value.

it seems already solved now, feel free to provide failing test case if you found other issue, thank you.
