Go SDK - Hello Couchbase code is broken.

Referring to
https://docs.couchbase.com/go-sdk/current/hello-world/start-using-sdk.html#hello-couchbase

The code sample is broken. The code sample is

func main() {

	cluster, err := gocb.Connect(

		"localhost",

		gocb.ClusterOptions{

			Username: "Administrator",

			Password: "password",

		})

	if err != nil {

		panic(err)

	}

The instruction text stays

Now you have the Go client installed, open your favourite text editor and try out the following:

If a user tries they will encounter three separate issues:

1) - No package or imports
2) - Contains the variable cluster which is not used. Go does not allow unused variables
3). The brackets to not match - there is a missing trailing bracket.

We should ensure that all code samples are runnable. Or at least make it clear that this is a short snippet that will not work on its own. (I much prefer the former option)

thanks
