Motivation:
Users should know as best as they can where they land when they click on the FileExporter link. Therefore, we want to let them know the wiki name where it lands
Task
For all WMF wikis, add a mediawiki message that renames "Export file" to "Import to Commons"
Technical notes
This will require an override message in the WikimediaMessages extension that is deployed on the WMF cluster.
