Give ‘group’ the same aggregation fields as ‘pagination’

[nagiek]

The group resolver is very powerful. I think we could make it even more powerful by allowing nested chains of grouping within a query.

We add the aggregation resolvers to pagination in schema/types/pagination.ts. Since the aggregation fields (distinct/group/max/min/sum) only use the edges argument, which is also available in group, why not add them to group as well?

Happy to help if you think it’s a good idea.
