Add updatedAt to ignored input fields in sdl creation

[leibowitz]

Currently only id and createdAt fields are skipped when creating and updating a record, when creating the sdl for a model. Therefore any non-null updatedAt field will cause the create to fail in the scaffold, because it is still defined in the graphql input type as required.

Note updatedAt is already ignored in the scaffold:

redwood/packages/cli/src/commands/generate/scaffold/scaffold.js

Line 34 in 5e51421

const NON_EDITABLE_COLUMNS = ['id', 'createdAt', 'updatedAt']

Just to be clear, here is what my schema looks like, and what scaffold sdl generated:
api/prisma/schema.prisma:

datasource DS {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

generator client {
  provider      = "prisma-client-js"
  binaryTargets = env("BINARY_TARGET")
}

model User {
  id                                Int                  @default(autoincrement()) @id
  createdAt                         DateTime             @default(now())
  updatedAt                         DateTime             @default(now()) @updatedAt
  full_name                         String
  email                             String
}

api/src/graphql/users.sdl.js:

import gql from 'graphql-tag'

export const schema = gql`
  type User {
    id: Int!
    createdAt: DateTime!
    updatedAt: DateTime!
    full_name: String!
    email: String!
  }

  type Query {
    users: [User!]!
    user(id: Int!): User!
  }

  input CreateUserInput {
    updatedAt: DateTime!
    full_name: String!
    email: String!
  }

  input UpdateUserInput {
    updatedAt: DateTime
    full_name: String
    email: String
  }

  type Mutation {
    createUser(input: CreateUserInput!): User!
    updateUser(id: Int!, input: UpdateUserInput!): User!
    deleteUser(id: Int!): User!
  }
`

And I get this error on create, in the scaffold:

An error has occurred
Field updatedAt of required type DateTime! was not provided.
