Bug Report

Subject	Details
Rector version	77f2def
PHP version	8.1.0

Trying to do a simple rename of a deprecated class with

    $services->set(RenameClassRector::class)
        ->configure([
            // /~https://github.com/doctrine/dbal/blob/master/UPGRADE.md#deprecated-dbalexception
            'Doctrine\DBAL\DBALException' => 'Doctrine\DBAL\Exception'
        ]);

Minimal PHP Code Causing Issue

The result is that you end up with a duplicated docblock

https://getrector.org/demo/1ec5b954-5e90-66f0-8d07-efa05ffbaaf2

Expected Behaviour

Rector is working correct and renaming the @throws tag in the docblock when there is no Attribute (in my case a Symfony Route Attribute, the second method in the demo class) - but DOESNT work correctly if there is an attribute following the docblock (the first method in the test case)

The result is that you end up with a duplicated docblock
