High-contrast icon set is missing a vpn connection icon

[Hardy Pottinger]

At first, when I connected to a VPN and didn't see the network icon gain a lock, I thought my VPN was broken... then I searched endlessly for a reason the icon wouldn't change, then I gave up. Then, it hit me, *maybe* the icon is missing from the high-contrast set, which I had recently changed to. So, I changed the icon set to Humanity, and there's the padlock when I connect to a VPN, just like I expected. I cannot find a repository for the high-contrast icon set, or I'd contribute one. So, I'll open this bug report instead. I do see a similar issue was raised for other missing icons: https://bugs.launchpad.net/ubuntu/+source/gnome-themes-standard/+bug/1644662 The VPN icon must have been missed.

I'm on the Bionic release of Ubunutu, I'm running Unity (I can't be bothered to re-learn Gnome, sorry).
