#### Describe the bug

Type definition for AxiosError is incorrect.  The definition was introduced in this commit:
https://github.com/axios/axios/pull/3645/files#diff-7aa4473ede4abd9ec099e87fec67fd57afafaf39e05d493ab4533acc38547eb8R137

When you look at the actual runtime payload it has a number type.  For example, a 401 error has `status` of `401` not `"401"` when you `JSON.stringify(error)`.

#### To Reproduce

A code snippet really doesn't make sense here, but you can see the JSON object that was constructed from the error object in the case that I observed.

```json
{
  "message": "Request failed with status code 401",
  "name": "AxiosError",
  "config": {
    "transitional": {
      "silentJSONParsing": true,
      "forcedJSONParsing": true,
      "clarifyTimeoutError": false
    },
    "transformRequest": [null],
    "transformResponse": [null],
    "timeout": 0,
    "xsrfCookieName": "XSRF-TOKEN",
    "xsrfHeaderName": "X-XSRF-TOKEN",
    "maxContentLength": -1,
    "maxBodyLength": -1,
    "env": {},
    "headers": {
      "Accept": "application/json",
      "Cache-Control": "no-cache",
      "Content-Type": "no-cache",
      "User-Agent": "axios/0.27.2"
    },
    "method": "get",
    "url": "https://somedomainrequiringauth.com/some-endpoint-requiring-auth"
  },
  "code": "ERR_BAD_REQUEST",
  "status": 401
}
```

#### Expected behavior

The definition should be a number.

 - Adapter HTTP
