[web] make useSortedENSResolvedUsers more permissive

Summary:
In the next diff we are going to want to use useSortedENSResolvedUsers to sort + resolve the thread members infos just like we did with the add friend list modal. However, right now useSortedENSResolvedUsers is currently typed so thread members can't use this hook since they use RelativeMemberInfo.

This diff updates useSortedENSResolvedUsers so that it can be used in both places

Test Plan: flow + confirmed that users are sorted correctly in the add users list + thread members list
