Archcraft errors out when Arch Linux ARM Keyring not installed by default

[tifasoftware]

To get past this screen, archlinuxarm-keyring had to be installed through pacman.

There may need to be a message suggesting that or have the script install it automatically, depending on what the best course of action is.

This version of Arch Linux ARM was installed through Archboot (https://archboot.com/) on a UTM Virtual Machine (Apple M1)
