forwardPorts not support "host:port" syntax

[mrdev023]

What happened?

When i try to use "[service_name]:[port]" with docker-compose config. I get json: invalid number literal, trying to unmarshal "\"db:5432\"" into Number

See https://containers.dev/implementors/json_reference/#general-properties

How can we reproduce the bug? (as minimally and precisely as possible)

My devcontainer.json:

{
    ...
    "forwardPorts": [
        3000,
        "db:5432"
    ],
    ...
}

Local Environment:

• DevPod Version: v0.1.4
• Operating System: linux
• ARCH of the OS: AMD64

DevPod Provider:

• Local/remote provider: docker

@mrdev023 thanks a lot for the issue! Oh true, seems like we missed that that is possible as well, should be an easy fix, we will fix that!
