Motivation
For this first MVP, the FileImporter should only be accessible through the link provided by the FileExporter. For testing, we currently use a specialPage where the url of the file you want to copy can be added. This should not go live
Acceptance Criteria
- The URL page of the FileImporter either does not exist, or is not available on production and mediawiki
- Remove Special:ImportFile from list of SpecialPages
- Remove input field from Special:ImportFile
- Show a message to the user explaining how to properly use the extension (link to help page on meta)
