Following up from T329043: Improved support for transferring translations between wikis.
Currently the import script does not import metadata (priority, transclusion information) from the page being exported to the target wiki. It also does not mark the page for translation automatically. The user has to do this manually.
Update the script to import the metadata, and mark the page for translation automatically.
Automatically marking the page for translation would require refactoring the code that is present in PageTranslationSpecialPage into a separate service.
