Update migration about parser rules about changelog-v5

[jamesgeorge007]

This config applies to all modules types. JS and e. g. JSON modules types. parser.requireEnsure is only valid for JS modules, while JSON module do not accept this option. They probably have to add a test: /\.[cm]?js$/ to make it only apply to JS module types.
