defaultForwardedPorts differs from User forwarded Ports #9715

• VSCode Version: 1.87.2
• Local OS Version: Mac OS
• Remote OS Version: Ubuntu 22.04
• Remote Extension/Connection Type: Containers (on Remote Server)

When using a default forwarded Port, forwards containing a different host don't work.
In my example i got a container inside a docker network next to a minio container and a database container. These are accessible inside my application where i remote into via database:3306 or minio:9000. I now want to automatically forward these ports whenever i connect to the remote container and therefore defined it inside the .vscode/settings.json.

	"remote.SSH.defaultForwardedPorts": [
		{
			"localPort": 3306,
			"name": "Database",
			"remotePort": "database:3306"
		},
		{
			"localPort": 9000,
			"name": "Minio",
			"remotePort": "minio:9000"
		},
		{
			"localPort": 9001,
			"name": "Minio (Web)",
			"remotePort": "minio:9001"
		}
	]

These entries don't work as expected and it fails to connect. However when i now remove the default forwarded ports and manually do the portforwarding through the interface (again using host:port), the services become available and function as it should be.

Steps to Reproduce:

1. Forward a port using settings.json remote.SSH.defaultForwardedPorts try to connect to container.
2. Remove said port forwards and do it manually, it works now.

In my opinion, the default ports should work exactly the same as the user forwarded ports.
