Multi-level nested type definitions in API lose hierarchy information when generating TypeScript files

[liuqiandev]

Describe the bug
When using multi-level nesting in type definitions in the API, the hierarchy information is lost when generating TypeScript files.

Original (原文): 在api中定义type时使用了多级嵌套，在生成ts文件时，导致层级丢失了层级信息

To Reproduce

1. API definition:

   Original (原文): api中的定义

   type (
    IdStruct {
        Id int64 `json:"id"`
    }
    NameStrcut {
        IdStruct
        Name string `json:"name"`
    }
    AgeStruct {
        NameStrcut
        Age int `json:"age"`
    })
   

2. Generated frontend code loses the first level IdStruct information:

   Original (原文): 生成的前端代码，丢失了第一层的IdStruct信息

   export interface AgeStruct {
    name: string
    age: number}
   

Environments (please complete the following information):

• goctl version 1.9.2
