erp5_hal_json_style: Make sure that keys in parallel_list_field are translated
To be compatible with xhtml, where in hash scripts like Base_getMultiListFieldPropertyDictList the category titles are not translated and translation happens in form rendering
Also: erp5_web_renderjs_ui_test: Add testParallelFieldListTranslation
to check the translation of category titles in parallel list field
