install docker as rootless docker to avoid root elevation

[perfecto25]

on current omarchy 4.1 - a non root user who is in docker group can elevate to root via known docker exploit

omarchy should ship a secure docker env using rootless docker configuration

ie sock should be like this

srw-rw---- 1 root docker-users 0 May 5 14:35 docker.sock

this is script I use on fedora to setup rootless docker

any user who needs docker access is added to docker-users group, not 'docker' group

install-rootless-docker.sh

Would also be nice if peoples first experience with docker on omarchy wasnt

docker run hello-world
permission denied while trying to connect to the docker API at unix:///var/run/docker.sock
