Describe the bug

On a request timeout Axios should throw an AxiosError, but when using the fetch adapter in Safari a TypeError: The DOMException.message getter can only be used on instances of DOMException is thrown.

userAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/26.0.1 Safari/605.1.15

To Reproduce

1. Use Safari
2. Make a request using the fetch adapter and make it timeout
3. On timeout it throws a TypeError: The DOMException.message getter can only be used on instances of DOMException

Sandbox with a request that always ends in timeout: https://codesandbox.io/p/sandbox/zkm26r

Code snippet

axios.get("https://fakeresponder.com/?sleep=50000", { adapter: "fetch", timeout: 2000 });

axios.get("https://api.example.com", { adapter: "fetch", timeout: 1 });

Expected behavior

Should throw an AxiosError with the timeout info, like the default adapter:

{
  message: "timeout 2000 of ms exceeded",
  code:  "ETIMEDOUT",
  name: "AxiosError"
}
