PHP8.4 hook processing is not supported.

[nikita-stena]

When using the new php8.4 syntax to implement hooks, the error "There was 1 validation error." is returned.

final class MainPageDTO extends SimpleDTO
{

    protected(set) DonationFormText $donationForm {
        get {
            return $this->donationForm;
        }
    }

    // or
    protected DonationFormText $donationForm {
        get {
            return $this->donationForm;
        }
    }
}
