ref(grouping): Include variant.contributes in grouping info JSON (#100893)

This adds each variant's `contributes` value to the JSON used in the grouping info section of the issue details page. Once this is deployed, a follow-up PR will switch the front end code to use this value (rather than the presence of a hash value) to determine whether or not the variant contributes, which will make handling certain special cases easier. (We'll be able to force a variant to show without incurring all of the side effects of adding a hash value.)
