Ubuntu 22.04 micro VM flist is outdated

[scottyeager]

If I deploy an Ubuntu 22.04 micro VM today from the Playground, it uses the flist: hub.grid.tf/tf-official-apps/threefoldtech-ubuntu-22.04.flist

This flist is not up to date with the changes in this repo and it has a pretty significant issue. The ssh-init zinit service definition is not set to oneshot. Therefore the script runs forever in a busy loop! It also overwrites any changes a user tries to make the authorized_keys file and invokes sshd when there's a dedicated service for that.

Let's replace the flist with one based on the latest Dockerfile in this repo, which does not have these issues.

@maxux Could you please promote flist https://hub.grid.tf/petep.3bot/threefolddev-ubuntu22.04-latest.flist.md instead of https://hub.grid.tf/tf-official-apps/threefoldtech-ubuntu-22.04.flist
it was tested and verified .
