fix(manager_versions.yaml): add support to ubuntu22
fix(manager_versions.yaml): add support to ubuntu22

for artifacts, we install mgmt agent, and as we
are adding support to Ubuntu 22.04 to 5.0 and 2022.1
we need the agent to be installed in it, to have the
job passing.
Full support shall still be done.
