NestJS集成Swagger调用createDocument报getVersioning非函数错误

• 重新安装@nestjs/swagger、swagger-ui-express依赖包，将项目所有依赖更新至最新版本，同步修改tsconfig.ts中metadata相关配置项后，服务运行报错
• 调试确认SwaggerModule类的createDocument函数调用前所有代码运行正常，所有配置项可正确读取，一旦执行createDocument方法，API服务直接崩溃
• 核心报错信息：applicationConfig.getVersioning is not a function at SwaggerExplorer.exploreRoutePathAndMethod
• 完整错误堆栈：

/home/prasanna/my_project/TapisProject/API/API/node_modules/@nestjs/swagger/dist/swagger-explorer.js:125
        const controllerVersion = this.getVersionMetadata(metatype, applicationConfig.getVersioning());
                                                                                      ^

@nestjs/swagger版本与NestJS核心包版本不匹配。高版本@nestjs/swagger的路由解析逻辑依赖@nestjs/core中ApplicationConfig实例的getVersioning()方法，更新依赖时如果仅升级swagger相关包，未同步升级@nestjs/common、@nestjs/core等NestJS核心套件，核心包中不存在该方法，就会触发上述类型错误。

• 同步升级NestJS核心依赖到与当前@nestjs/swagger匹配的版本，根据自己使用的包管理器执行对应命令：
  • npm用户执行：npm install @nestjs/common@latest @nestjs/core@latest @nestjs/platform-express@latest
  • pnpm用户执行：pnpm add @nestjs/common@latest @nestjs/core@latest @nestjs/platform-express@latest
  • yarn用户执行：yarn add @nestjs/common@latest @nestjs/core@latest @nestjs/platform-express@latest
• 如果升级后仍存在异常，先删除项目下的node_modules目录、对应包管理器的锁文件（package-lock.json/pnpm-lock.yaml/yarn.lock），重新执行全量依赖安装
• 依赖安装完成后重启项目，swagger文档生成逻辑即可恢复正常
