This change updates the classes Message, MessageCode, Template, LocatedMessage, and FormattedMessage so that they uniformly refer to error message text using the terminology `problemMessage` and to correction suggestions using the terminology `correctionMessage`. This brings them into alignment with the names we've decided to use to unify the structure of front_end and analyzer, and makes them match the names used in the anlayzer and front end's `messages.yaml` files.
