What happened?

Hello,

when using kr8s.objects.Pod().portforward to reach PostgreSQL with psycopg, we are getting the following at the end of a successful communication with the PostgreSQL server:

Unhandled exception in client_connected_cb
transport: <_SelectorSocketTransport closed fd=11>
  + Exception Group Traceback (most recent call last):

Should ConnectionResetError be added to the exceptions @ https://github.com/kr8s-org/kr8s/blob/v0.18.1/kr8s/_portforward.py#L238 or handled for https://github.com/kr8s-org/kr8s/blob/v0.18.1/kr8s/_portforward.py#L247 like it is present for sending @ https://github.com/kr8s-org/kr8s/blob/v0.18.1/kr8s/_portforward.py#L255 ?

Anything else?
