Add WireGuard PrivateKey/PresharedKey rule

[gemesa]

This is a rule I regularly use to look for WireGuard .conf files (specifically private and preshared WG keys). Maybe it makes sense to add it to the defaults. I generated the 2 keys in the example myself just for this purpose.

Thank you @gemesa! This looks really good. This will allow Nosey Parker to detect more secrets with precision.

Would you please split this new WireGuard PrivateKey/PresharedKey rule into two new rules? They are conceptually different things, even if they have the same format. WireGuard Private Key and WireGuard Preshared Key are good names for them.

I split them and fixed the review findings, please check it out.
