Go doesn't update version if go is already installed

[craiglpeters]

The go feature ignores the current version, and the version option specified, when go is already installed.

Steps to reproduce

Create a .devcontainer as below

{
    "features": {
        "ghcr.io/devcontainers/features/go:1": {
            "version": "1.18"
        }
    }
}

Start a codespace using the universal container image which already has go installed

At the terminal note that the version of go does NOT match the option specified in the go feature

$ go version
go version go1.19.2 linux/amd64

Check the creation logs and note it says Go already installed. Skipping
