Older versions of Windows used to be able to detect a UPnP-enabled router and expose it as an “internet gateway” where you can manage the UPnP port forwarding assignments.
What happened to that functionality in Windows 10? If it’s no longer built-in, is there a 3rd-party alternative?

Manually managing UPnP port forwarding assignments is a feature of the past. Windows 10 has an API for that, so almost all applications nowadays open their own ports without user intervention.
If you have an older application and need to port-forward your own ports, the only built-in tool you can use isnetshwith a syntax like:
netsh interface portproxy add v4tov4 listenport=4422 listenaddress=192.168.1.111 connectport=80 connectaddress=192.168.0.33If netsh is not useful for your purpose, there are many free tools
for opening UPnP ports on the router.
Here is a small list:
I have not used any of these tools and cannot recommend one above the others.
MS Store offers free UPnP analyzer:
