Can't install Go package

The [command](https://github.com/cdklabs/cdk-stacksets?tab=readme-ov-file#go) in the readme to install the Go package fails with the error:

```
>> go get cdk-stacksets-go
go: malformed module path "cdk-stacksets-go": missing dot in first path element
```

Go mod tidy produces

```
>> go mod tidy
go: finding module for package github.com/cdklabs/cdk-stacksets
go: teststack imports
github.com/cdklabs/cdk-stacksets: module github.com/cdklabs/cdk-stacksets@latest found (v0.0.150), but does not contain package github.com/cdklabs/cdk-stacksets
```

I can't seem to find the package in https://pkg.go.dev either.

Is there a go build for this construct?
