[Bug]: `ModelInfo::getVirtualAttributes()` ignores accessor method return types

[vinpogo]

What happened?

I have a model accessor that's clearly typed as nullable:

class Post extends Model
{
    public function getExcerptAttribute(): ?string
    {
        return $this->body ? substr($this->body, 0, 100) : null;
    }
}

When I expose this through a JsonResource and generate the OpenAPI spec, the field comes out as a required, non-nullable string — even though the PHP return type explicitly says it can be null.

I tried a few things to nudge Scramble toward the right type, all without effect:

• Using : string | null instead of : ?string on the accessor
• Adding @property-read string|null $excerpt to the model's class docblock

Only an inline // @var string|null directly above the field in toArray() produces the correct nullable type. That works as a workaround, but it means every accessor-backed field across the codebase needs a redundant annotation that just restates what the PHP signature already says.
