[Typescript Axios] Type annotations are escaping special characters

Description

I am using the typescript-axios preset to generate the API client. The generated code is using HTML escaping which is causing certain type annotations, particularly ones which use special characters, to not get recognized by Typescript in my client codebase.

Below is what the outputted client code looks like:

export interface ServerpbInvoice {
    /**
     * @inject_tag: validate:\"required\"
     * @type {Array<ServerpbInvoiceItems>}
     * @memberof ServerpbInvoice
     */
    items: any;
    ...
}

Swagger-codegen version

3.0.23

Swagger declaration file content or url

{
    ...
    "definitions": {
        "serverpb.Invoice": {
            "type": "object",
            "required": [
                ...
            ],
            "properties": {
                ...
                "items": {
                    "description": "@inject_tag: validate:\"required\"",
                    "type": "array",
                    "items": {
                        "$ref": "#/definitions/serverpb.InvoiceItems"
                    }
                },
            }
        }
    }
    ...
}

Command line used for generation

swagger-codegen generate -i docs/swagger.json -l typescript-axios -o ./generated

Steps to reproduce

1. Run the command described above to generate an API client
2. Reference a property with escaped special characters in the type annotation
3. Run the Typescript compiler

Related issues/PRs

I could not find any.

Start by running the stated swagger-codegen command with docs/swagger.json and inspect the typescript-axios output in generated. Trace where the items type annotation is rendered and verify that special characters remain usable by the TypeScript compiler; done means the generated client compiles without the escaping issue.
