Enhance npx prisma init: Pre-define basic model in schema.prisma for a smoother prisma studio experience

[Milan-960]

Bug description

Currently, when running npx prisma init, a user encounters an error message if they attempt to launch prisma studio without defining any models in their schema.prisma file. While the error message clearly guides the user towards defining a model, it can be a minor hurdle for beginners.

Suggestion:

To provide a more seamless experience for new users, consider incorporating a basic model pre-definition within the schema.prisma file generated by npx prisma init. This model could be something simple like:

model User {
  id     Int      @id @default(autoincrement())
  email  String   @unique
  name   String?
}

Benefits:

• Reduced Friction for New Users: This pre-defined model would allow users to immediately explore prisma studio without encountering the initial error message, streamlining their onboarding journey.
• Learning Opportunity: The basic model serves as a starting point for users to understand the concept of models and schema definition in Prisma. They can then customize or extend this model as their project evolves.

Additional Points:

• Configuration Option: If providing a pre-defined model is deemed unnecessary, consider adding a configuration option within npx prisma init that allows users to choose whether or not to include a basic model.
• Error Handling Improvement: Explore ways to enhance the error message when no models are defined. This could involve providing more specific guidance for defining a model alongside the link to the documentation.

How to reproduce

1. Go to your project directory.
2. Initialize a new Prisma project:

   npx prisma init

 3.Start Prisma Studio:
```bash
  npx prisma studio
