Based on a quick Google search, they do appear to be completely synonymous. I think we should prefer as the main tag and make a synonym, because "habitable" is a more plain rendering of the concept whereas "goldilocks" requires an understanding of the British fairy tale and how the parallel is drawn ("not too hot" and "not too cold").
