Structured content auto language (#2131)
* Pass JapaneseUtil instance to StructuredContentGenerator * Move body of createStructuredContent to an internal function * Create _createStructuredContentGenericElement * Wrap structured content in a <span> * Change _createStructuredContent to _appendStructuredContent * Add public appendStructuredContent function * Add missing return * Remove unused _createDocumentFragment * Automatically assign lang=ja for content with Japanese characters without an explicit language * Add test
