Feat: Add lint rule to enforce modules to have register/registerAsync and/or forRoot/forRootAsync

[tolgap]

Description

We should detect whether module classes that return a DynamicModule are named register, registerAsync, forRoot or forRootAsync.

Acceptance Criteria

Incorrect:

@Module({})
export class ProductsModule {
  static create(options): DynamicModule { // ⚠️ `Dynamic module methods must be named `register/registerAsync` or `forRoot/forRootAsync`
    return {
      module: ProductsModule,
      imports: [TypeOrmModule.forFeature([Product]),
      providers: [/* ... */],
    }
  }

  static registerAsync(options): DynamicModule { // ✅ 
    return {
      module: ProductsModule,
      imports: [TypeOrmModule.forFeature([Product]),
      providers: [/* ... */],
    }
  }
}

Correct:

@Module({})
export class ProductsModule {
  static register(options): DynamicModule { // ✅ 
    return {
      module: ProductsModule,
      imports: [TypeOrmModule.forFeature([Product]),
      providers: [/* ... */],
    }
  }

  static registerAsync(options): DynamicModule { // ✅ 
    return {
      module: ProductsModule,
      imports: [TypeOrmModule.forFeature([Product]),
      providers: [/* ... */],
    }
  }
}
