Point "View support docs" at online support section for Beta 1

Since we've bumped #347 to 1.1.0-beta, let's temporarily point "view support docs" in the Help tab here for 1.0.0-beta instead:

• https://support.torproject.org/tor-vpn

It would also be great if we could restore the trailing ↗️ icon on the right of the card too, to indicate that this is an external link. However this isn't crucial.
