The "Download Tor Source Code" page is mixing source code and win32 binaries
The new "Download Tor Source Code" page is confusing because it provides links for Windows, MacOS and Linux. But the source code is platform independent, so there should be only one link that is good for any platform.
The OSX and Linux links are pointing to the source code, however the Windows one is not pointing to the source code, but to an old version of the expert bundle.
If in addition to the source code, we want to provide links to the Windows Tor binaries (which we used to call the "Expert Bundle" on the old website), the correct download links should be (for 32 and 64 bits versions): https://dist.torproject.org/torbrowser/8.0.8/tor-win32-0.3.5.8.zip https://dist.torproject.org/torbrowser/8.0.8/tor-win64-0.3.5.8.zip
Using variables from databags/versions.ini to create the URL, I think 8.0.8 is torbrowser-stable->version, and 0.3.5.8 is tor-win32-stable->version.
