Fix comma bug in wg config, Dockerfile dependencies, added 'update' to Makefile

[samsipe]

Description

This is three quick fixes I figured I would share with the community.

1. The wireguard config generator had a comma error, fixed @ roles/wireguard/defaults/main.yml
2. Docker Image wouldn't build on any OS (added cargo dependency and it builds on MacOs and Ubuntu) @ Dockerfile
3. Added a quick and easy Make Command for updating users in accordance with the documentation @ Makefile
   • I also changed the Makefile to work on any OS using $$(pwd) format.

Motivation and Context

Couldn't find any open issues on this but this fixes the issues above. This makes it easier for those deploying Algo from Docker, especially if they want to build their own docker image.

How Has This Been Tested?

Deployed a VPN to AWS and Linode using these changes from GitLab CI/CD, Ubuntu, and MacOS.

It looks like all of the lint check annotations were from unchanged files... not sure why Github just caught them now.
