Use the regular navbar for /download

Context: #108
The navbar-min has an issue where the language selection dropdown
horizontal-overflows the page. The original fix (adding padding) worked,
but we've decided to use the normal navbar to fix the overflow and
present the full navigation to users on the download page.
