docs: fix README examples for follow, vote, reaction jobs

- follow.follow requires payload dict, not username string
- vote.votecast uses 'vote' not 'voteType', and has parent structure
- reaction.reacttosomething uses 'reaction' and 'parent', not 'reactionType' and 'objectPK/SK'
- feed.following -> feed.followingfeed
- branch.listbyname doesn't take prefix parameter
