Hello,

On the [install page of the website](https://www.wireguard.com/install/), the default pin config smartly deprioritizes Sid after adding the repository. However, it seems this causes the wireguard packages to be non-upgradable. After speaking with someone on IRC about this, I can't think of a reason why we wouldn't want to be able to upgrade the wireguard packages. So, I'd like to propose the following addition to the pinning configuration written in the instructions (unified diff follows):

==========================

# apt update
# apt install wireguard

==========================

This preserves the general priority of 90 for *, but it also sets any package starting with wireguard to 500, which matches the default priority used in the PPAs.

The only reason I chose a regex match here is in case any additional wireguard packages get added later, other than wireguard, wireguard-dkms, and wireguard-tools. Otherwise, the Package line could read:

Package: wireguard wireguard-dkms wireguard-tools

Anyone have any objections to this approach? Also, is there a repo for the website I can fork and PR this to?

Thank you in advance.
