generating client with Axios Template and useAbortSignal true imports deprecated CancelToken type

[stephenmetzger99]

Describe the bug

I am generating a typescript api client for my dotnet api. I am using the axios template.

The bug I am running in to is when I use useAbortSignal: true to generate my client, it still generates an import for CancelToken at the top of the client:

import type { AxiosInstance, AxiosRequestConfig, AxiosResponse, CancelToken } from 'axios';

My understanding is that with Axios they had their own implementation of cancellation but it was deprecated after AbortSignal debuted.

This is an issue because the generated api client has an error in it since CancelToken is deprecated and no longer available.

I made my own copy of File.liquid locally and changed it from:

{%- if Framework.IsAxios -%}
import axios, { AxiosError } from 'axios';
import type { AxiosInstance, AxiosRequestConfig, AxiosResponse, CancelToken } from 'axios';
{%- endif -%}

to

{%- if Framework.IsAxios -%}
import axios, { AxiosError } from 'axios';
import type { AxiosInstance, AxiosRequestConfig, AxiosResponse } from 'axios';
{%- endif -%}

And that fixed my problem temporarily, but ideally I don't want to use my own .liquid.
