fix: ApiVersion check fix (#193)

- fixes api version comparison

## This PR
Version check was failing in kube sync.
CRD APIVersion = `core.openfeature.dev/v1alpha1`
v1alpha1.GroupVersion.Version = `v1alpha1`

replaced with a constructed group version: `fmt.Sprintf("%s/%s",
v1alpha1.GroupVersion.Group, v1alpha1.GroupVersion.Version)`
