CLN: Use https for @tm.network
- [x] ref #36467

 AssertionError: Caused unexpected warning(s): [('ResourceWarning', ResourceWarning("unclosed <ssl.SSLSocket fd=18, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=6, laddr=('10.20.0.43', 54722), raddr=('**172.217.204.95**', 443)>"), ), 

**This is a google address** -> which leads me to believe this resource warning is coming from our `network` function in `_testing.py` since it calls `urllib.request.urlopen("https://www.google.com")` 

Note: this doesn't solve the problem but we should use https. (Avoids a redirect)
