Fix for Image Update not including env changes.
Added python-is-python3 python3.10-venv to aid in python development.
Added software-properties-common so we can take advantage of the new Meshtastic PPA.
clone_repos now tries 3 times on each repo and exits if it fails. Thanks to spudgunman on discord now script checks for Ubuntu 22.04 and checks if repos already exists on SDk Install.
Thanks to josh_32850_99879 on discord for figuring out how and when to use mkenvimage and .env.txt to make the image able to expand rootfs on first boot.
Put in some checks, chroot script injection, fixed menu and dependencies, moved initial chroot commands to chroot script, fixed cli args, updated usage and added new args including --chroot-script
