Update prisma.md

[RyuNIshimura]

I updated it because it didn't work when I implemented it the same way as in the documentation.

Error

app_1    | [Nest] 42  - 08/27/2021, 11:38:49 AM   ERROR [ExceptionHandler] Nest can't resolve dependencies of 
the AppController (AppService, ?). Please make sure that the argument UserService at index [1] is available 
in the AppModule context.

Replace the contents of the app.module.ts file with the following code and it will work.

import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { PrismaService } from './prisma.service';
import { UserService } from './user.service';
import { PostService } from './post.service';

@Module({
  imports: [],
  controllers: [AppController],
  providers: [AppService, PrismaService, UserService, PostService],
})
export class AppModule {}

@jmcdo29 I stumbled on the same. I'd like to see it merged for the sake of the newbies.

I don't find this addition helpful (it should be obvious after reading other chapters).
