1.57.2

(fix): Fix JSON deserialization of date and datetime values nested in containers. Lists, sets, and string-keyed maps of dates (including optional containers and aliases of containers) are now unmarshaled through the internal date wrappers, so date-only values such as "2002-08-28" no longer fail with parsing time "2002-08-28" as "2006-01-02T15:04:05Z07:00".
