Fix `connect.host` setting being ignored by debugpy (#43190)

Andrew Farkas and Cole Miller created 1 month ago

Closes #42727

Unfortunately we can only support IPv4 addresses right now because
`TcpArguments` only supports an IPv4 address. I'm not sure how difficult
it would be to lift this limitation.

Release Notes:
