[Typescript Axios] Bug generating Map or Map<String,String> Model

Description

我是一名前端开发者，非常喜欢Swagger-Codegen带来的前端ts代码生成能力，我经常用来将后端接口文档的api-docs生成Typescript-Axios的代码，但是遇到了问题，当后端的Coltroller层返回值是Map的时候，Swagger-Codegen直接报错了（translate：I am a front-end developer and I really enjoy the front-end TS code generation capability brought by Swagger Codegen. I often use API docs in back-end interface documents to generate Typescript Axios code, but I encountered a problem. When the Coltroller layer in the backend returns a Map value, Swagger Codegen directly reports an error）

当尝试通过服务 'https://generator3.swagger.io/api/generate' 获取Typescript-Axios代码时，服务错误为：（translate：When attempting to access the service 'https://generator3.swagger.io/api/generate' When obtaining Typescript Axios code, the service error is:

Error generating typescript-axios code : Could not process model 'Map脗芦string,string脗禄'.Please make sure that your schema is correct!

Steps to reproduce

Suggest a fix/enhancement

Start with the supplied OpenAPI 3.0.1 schema and reproduce generation through the generator3.swagger.io service using the typescript-axios generator. Investigate how the Map«string,string» schema with additionalProperties is handled; done means the example generates Typescript-Axios code without the reported model-processing error.
