Creating some space to host Tor Browser nightly updates
We need a space to upload and make available the Tor Browser nightly updates, for #18867 (moved).
We could reuse the same name, https://nightlies.tbb.torproject.org/. An .onion address would be nice too.
Space needed will be ~10G in the beginning (starting with only 5 locales, but we'll maybe want to increase that number in the future).
