Incorrect Include typings when having models called `X` and `XUpdate`

Bug description

When having two models called X and XUpdate, the generated types for include parameters of XUpdate are incorrect.

How to reproduce

Example (only relevant fields included):

model Product {
  id      String          @id @default(uuid())
  updates ProductUpdate[] @relation(name: "ProductUpdates")
}

model ProductUpdate {
  id        String  @id @default(uuid())
  productId String
  product   Product @relation(name: "ProductUpdates", fields: [productId], references: [id])
}

Then, when querying another model that has a relation with ProductUpdate:

prisma.orderItem.findUnique({
  where: {
    id,
  },
  include: {
    productUpdate: {
      include: {
        product: true,
      },
    },
  },
})

I get the following error:

Looking at the generated types, this seems to be because the productUpdate field in OrderItemInclude has type ProductUpdateArgs, which are the arguments for an update operation on a Product model, instead of the args without action of the ProductUpdate model.

Expected behavior

The type of OrderItemInclude.productUpdate should be related to the ProductUpdate model, not the Product model. Consequently there should not be a type error in this situation.

Sorry for the late reply here. This got buried in my notifications.

I can confirm the conflict and marking this as candidate.
