Enum schema missing information on multiple specifications

Current behavior

Our team has been experiencing this issue since we upgraded from @nestjs/[email protected], it is a weird one and took time to find. It appears that there is an issue with with multiple specifications. It fails to create the enum for specifications for the following specifications. It will show the enum only in the first specification when the enum is define with both ApiQuery and ApiProperty.

Minimum reproduction code

https://github.com/DJCrossman/nest-swagger-multi-spec-enums-bug

Steps to reproduce

1. nest new project-name

2. cd project-name

3. npm install @nestjs/swagger

4. nest g module cats

5. nest g class cats/cat --flat

6. Edit src/cats/cat.ts, to have CollarColorEnum and ApiProperty:

   import { ApiProperty } from '@nestjs/swagger';
   
   export enum CollarColorEnum {
     'red' = 'red',
     'green' = 'green',
     'blue' = 'blue',
   }
   export type CollarColor = keyof typeof CollarColorEnum
   
   export class Cat {
     @ApiProperty({ enum: CollarColorEnum, enumName: 'CollarColor' })
     collar_color: CollarColor;
   }

7. nest g controller cats

8. Edit src\cat\cat.controller.ts, to have find endpoint:

   import { Controller, Get } from '@nestjs/common';
   import { ApiQuery, ApiResponse, ApiTags } from '@nestjs/swagger';
   import { Cat, CollarColorEnum } from './cat';
   
   @ApiTags('cats')
   @Controller('cat')
   export class CatsController {
     @Get()
     @ApiQuery({ enum: CollarColorEnum, enumName: 'CollarColor' })
     @ApiResponse({ status: 200, type: [Cat] })
     find() {
       return [];
     }
   }

9. Initialize Swagger with multiple specifications:

   import { NestFactory } from '@nestjs/core';
   import { DocumentBuilder, SwaggerModule } from '@nestjs/swagger';
   import { AppModule } from './app.module';
   import { CatsModule } from './cats/cats.module';
   
   async function bootstrap() {
     const app = await NestFactory.create(AppModule);
   
     const options = new DocumentBuilder()
       .setTitle('Cats example')
       .setDescription('The cats API description')
       .setVersion('1.0')
       .addTag('cats')
       .build();
   
     const catDocument = SwaggerModule.createDocument(app, options, {
       include: [CatsModule],
     });
     SwaggerModule.setup('api/cats', app, catDocument);
   
     const secondOptions = new DocumentBuilder()
       .setTitle('Broken example')
       .setDescription('The cats API with missing enum')
       .setVersion('1.0')
       .addTag('broken')
       .build();
   
     const document = SwaggerModule.createDocument(app, secondOptions, {
       include: [CatsModule],
     });
     SwaggerModule.setup('api', app, document);
     await app.listen(3000);
   }
   bootstrap();

10. npm run start:dev

11. Go to http://localhost:3000/api-json

Expected behavior

The enum schema CollarColor should be defined with enum values and not only appear as type string in the specification. It should be expected that both the http://localhost:3000/api-json specification and http://localhost:3000/api/cats-json should be identical.
