Successful introspection removes comments from schema.prisma

Before:

// This is your Prisma schema file,
// learn more about it in the docs: https://pris.ly/d/prisma-schema

// The `datasource` block is used to specify the connection to your DB.
// Set the `provider` field to match your DB type: "postgresql", "mysql" or "sqlite".
// The `url` field must contain the connection string to your DB.
// Learn more about connection strings for your DB: https://pris.ly/connection-strings
datasource db {
  provider = "sqlite" 
  url      = "sqlite:./chinook.db"
}
// Other examples for connection strings are:
// SQLite: url = "sqlite:./dev.db"
// MySQL:  url = "mysql://johndoe:johndoe@localhost:3306/mydb"
// You can also use environment variables to specify the connection string: https://pris.ly/prisma-schema#using-environment-variables

// By adding the `generator` block, you specify that you want to generate Prisma's DB client.
// The client is generated by runnning the `prisma generate` command and will be located in `node_modules/@prisma` and can be imported in your code as:
// import { Prisma Client } from '@prisma/client'
generator client {
  provider = "prisma-client-js"
}

// Next steps:
// 1. Add your DB connection string as the `url` of the `datasource` block
// 2. Run `prisma2 introspect` to get your data model into the schema
// 3. Run `prisma2 generate` to generate Prisma Client JS
// 4. Start using Prisma Client JS in your application

After:

generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "sqlite"
  url      = "sqlite:./chinook.db"

👀 definitely still would be nice to have this, otherwise don’t support comments in the file at all-

There is no original model, so that is not really the point here (although I of course understand the underlying difficulties).
