Bug description

ReIntrospection doesn't retain @updatedAt attribute.

How to reproduce

1. schema.prisma

model User {
  id String @id
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
}

2. Either migrate or use the following SQL

CREATE TABLE `User` (
  `id` varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,
  `createdAt` datetime(3) NOT NULL DEFAULT CURRENT_TIMESTAMP(3),
  `updatedAt` datetime(3) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

3. Run prisma introspect --experimental-reintrospection

4. The @updatedAt attribute is lost.

Expected behavior

@updatedAt should be retained.
