The download dialog should have a link that takes the user to https://ws-export.wmcloud.org/, with the title and lang prefilled, just like the existing "Other formats" link in the sidebar.
This allows users to be informed that there are other options and formats available.
- At the bottom of the download pop-up, display the following:
- Text: "Looking for a different format?" in light grey
- Text is aligned with text such as PDF, MOBI, etc
- When clicked, the link redirects user (in a separate tab) to the Wikisource Export page with language code and book title pre-populated in relevant fields
