go: Correct module path

Without this, the module cannot be go installed.

go install github.com/anderseknert/kube-review@latest
go: downloading github.com/anderseknert/kube-review v0.3.0
go: github.com/anderseknert/kube-review@latest: version constraints conflict:
        github.com/anderseknert/kube-review@v0.3.0: parsing go.mod:
        module declares its path as: kube-review
                but was required as: github.com/anderseknert/kube-review
