Installation works in Ubuntu 23 with minor issues

Thanks for the project, I just installed it and looks great!

I was able to install in Ubuntu 23 but I had to remove openresolv from the wireguard dependencies. Looks like it's not necessary in the newer verions.

Feature request:

Issue: the install script resets the repo folder.

Solution: Add an option to the install script to not delete/reset the repo folder (/opt/mistborn)
