On Windows, above commit broke dns_hacks.py with dnspython==2.0.0 and 2.1.0.
Newer dnspython works.
Root cause not immediately obvious. Probably not worth debugging, I will just bump the required version instead.

With dnspython==2.0.0, the log gets spammed and dns fails:
```
$ python3 -m pip install --user "dnspython==2.0.0"

 10.59 | E | asyncio | Exception in callback _ProactorBasePipeTransport._call_connection_lost(None)
handle: <Handle _ProactorBasePipeTransport._call_connection_lost(None)>

  File "...\Python310\site-packages\dns\_asyncio_backend.py", line 38, in connection_lost
    self.recvfrom.set_exception(exc)

```
With dnspython==2.1.0, no more log spam but all dns resolutions time out:
```
$ python3 -m pip install --user "dnspython==2.1.0"
