Config withPhpSets does not work with composer require php-64bit

Bug Report

Subject	Details
Rector version	1.2.2

If I use withPhpSets without arguments on project that has in composer.json php defined only as require.php-64bit then I'll get error.

 [ERROR] We could not find local "composer.json" to determine your PHP version.                                       
         Please, fill the PHP version set in withPhpSets() manually. 

Minimal PHP Code Causing Issue

rector.php

return RectorConfig::configure()
    ->withPhpSets();

composer.json

{
    "require": {
        "php-64bit": "8.1.*",
    }
}

Expected Behaviour

In \Rector\Php\PhpVersionResolver\ProjectComposerJsonPhpVersionResolver::resolve should be added read for php-64bit instead of just php.

That means this line should be changed for example like this

-$requirePhpVersion = $projectComposerJson['require']['php'] ?? null;
+$requirePhpVersion = $projectComposerJson['require']['php'] ?? $projectComposerJson['require']['php-64bit'] ?? null;
