As an example, https://github.com/kubernetes-sigs/kustomize/releases/download/kustomize%2Fv5.6.0/kustomize_v5.6.0_darwin_amd64.tar.gz is the type of URL not expected by this tool. The tag is kustomize/v5.6.0 so it needs to be URL encoded. Besides that, extracting version from kustomize/v5.6.0 here does not work.
