Ubuntu 22 Support about cloudblock

[Dviros]

When running on 22.04 on a brand new Azure machine, I get the following error:

TASK [Docker apt repo] **************************************************************************************************************************************************************
task path: /opt/cloudblock/playbooks/cloudblock_azure.yml:36
fatal: [localhost]: FAILED! => {"changed": false, "msg": "Failed to update apt cache: W:GPG error: https://download.docker.com/linux/ubuntu jammy InRelease: Unknown error executing apt-key, E:The repository 'https://download.docker.com/linux/ubuntu jammy InRelease' is not signed."}

Seems like these are the correct permissions for the docker.asc key:

• sudo chmod a+r /etc/apt/keyrings/docker.asc

Spun up a new 22.04 machine based on the latest version mentioned in the Azure deployment file and it works.
