In the extension CleanChanges, in composer.json file, the name of the extension is : "mediawiki/cleanchanges", but according to composer specifications, it should be "mediawiki/clean-changes" in order that the directory name of the extension is set to "CleanChanges"
( Currenlty, if we install the extension using composer, it installs it into a bad named "Cleanchanges" directory )
It should so be renamed, but if peoples already use the wrong name, it will break their link
