fix: upgrade base server image from Ubuntu 18.04 to Ubuntu 22.04

It was failing as 18.04 was previously deprecated and has been removed from DigitalOcean/Hetzner APIs:

• https://docs.hetzner.cloud/changelog#2023-08-31-ubuntu-1804-is-unavailable-for-new-orders

On top of just updating the base image we use, we had to make some adjustments to have servers properly provision on 22.04:

• Wait for apt to unlock before installing / updating packages for both sudo and installed user. Update the function to check for locks as it differs from 18.04
• Install Node v18 that's needed for latest core
• Install additional base packages that were previously installed out of the box (make, net-tools needed for ifconfig, build-essential needed to install the core from Yarn, likely due to gcc)
• Update origin for unattended upgrades to jammy (22.04)
