sync API prop names: rename client to queryClient

[milahu]

mostly its queryClient
persistQueryClientSubscribe: props.queryClient

sometimes its client
QueryClientProvider: props.client

ideally its always queryClient
so i can avoid translation steps like

mergedProps.queryClient = mergedProps.client

thanks, I'll keep in mind for v5, but I would opt for client instead of queryClient. Most functions have the name queryClient in the name already, like QueryClientProvider or persistQueryClientSubscribe. But I'll think about it.
