[`flake8-bandit`] fix S113 false positive for httpx without `timeout` argument (#12213)
## Summary
S113 exists because `requests` doesn't have a default timeout, so
request without timeout may hang indefinitely
> B113: Test for missing requests timeoutī
This plugin test checks for requests or httpx calls without a timeout
specified.
>
> Nearly all production code should use this parameter in nearly all
requests, **Failure to do so can cause your program to hang
indefinitely.**
But httpx has default timeout 5s, so S113 for httpx request without
`timeout` argument is a false positive, only valid case would be
`timeout=None`.

> HTTPX is careful to enforce timeouts everywhere by default.

> The default behavior is to raise a TimeoutException after 5 seconds of
network inactivity.
