When using PHP attributes it incorrectly "builds" the Fully Qualified Class Name

See https://psalm.dev/r/4dc3c5409a

This might have to do with #6197 and the linked PR #6204

I found these snippets:

<?php

namespace NamespaceOne {
    use Attribute;
    
    #[Attribute(Attribute::TARGET_CLASS)]
    class FooAttribute
    {
        /** @var class-string */
        private string $className;

        /**
         * @param class-string<FoobarInterface> $className
         */
        public function __construct(string $className)
        {
            $this->className = $className;
        }
    }

    interface FoobarInterface {}

    class Bar implements FoobarInterface {}
}

namespace NamespaceTwo {
    use NamespaceOne\FooAttribute;
    use NamespaceOne\Bar;
    
	#[FooAttribute(className: Bar::class)]
	class Baz {}
}

Psalm output (using commit 7e137f5):

ERROR: InvalidArgument - 30:28 - Argument 1 of NamespaceOne\FooAttribute::__construct expects class-string<NamespaceOne\FoobarInterface>, NamespaceTwo\NamespaceOne\Bar::class provided
