[Tor www-team] Add options for 32 bit linux download on the main download page

Hello, www-team!

The recent (2019) redesign of the website confused me a bit. For example the download page on the main page (https://www.torproject.org/download/) provides no option to select Tor Browser target architecture, users must manually go to https://dist.torproject.org/torbrowser/9.5.3/ (no link points to this address) to download their specific architecture if they do not have 64-bit Linux.

It would be useful, at least in my humble opinion, to either detect user's architecture with some Javascript code or to provide an additional button for 32-bit Linux downloads of the Tor Browser Bundle.

Thanks and regards!
