Subject: [PATCH] feat(feeds): add reaction write outcome fields

Adds outcome, previous_reaction_type and counter_delta to
AddReactionResponse and AddCommentReactionResponse, from the v2 serverside
spec (GetStream/chat#17241).

Scoped to just these two interfaces rather than a full regeneration: a
wholesale regen also pulls in every other spec change since the last
refresh, which is a much wider surface than this needs.
