#### Describe the bug

I tried to use the function added in #4248 with TypeScript, but got the following error.

```
Property 'clear' does not exist on type 'AxiosInterceptorManager<AxiosRequestConfig<any>>
```

#### To Reproduce

Execution is possible, but type checking fails.

```ts
import axios from "axios";

axios.interceptors.request.clear()
```

#### Expected behavior

Successful type check

#### Environment
 - Axios 1.0.0
 - TypeScript 4.8.4

test/typescript/axios.ts
if (axios.isAxiosError(error)) {
      const axiosError: AxiosError = error;
    }
  });
axios.toFormData({x: 1}, new FormData());
axios.get('/user', {signal: new AbortController().signal});
axios.get('/user', {
    transformRequest: (data, headers) => {
        headers.setContentType('text/plain');
        headers['Foo'] = 'bar';
    },
    transformResponse: (data, headers) => {
        headers.has('foo');
    }
});
axios.get('/user', {
  maxRate: 1000
});
axios.get('/user', {
  maxRate: [1000, 1000],
});
axios.get('/user', {
  onUploadProgress: (e) => {
    console.log(e.loaded);
    console.log(e.total);
    console.log(e.progress);
    console.log(e.rate);
  }
