Seems overly complicated. I installed Docker CE right from docker.com in Ubuntu 20.04 on WSL2 with only 2 'issues' both due to lack of systemd:
1.) Missing cgroups under /sys/fs/cgroup/systemd
mkdir /sys/fs/cgroup/systemd
mount -t cgroup -o none,name=systemd cgroup /sys/fs/cgroup/systemd
2.) No launch at 'startup'
put the docker start in your .bashrd
Also, 'Kind'(1) works really well for setting up K8s envs in WSL2
