Remove unhealthy Job condition for OS updates

[agners]

Proposed change

An outdated Home Assistant OS might be the reason for the system to be declared unhealthy (e.g. due to an old Docker version). Operating system updates are fairly self contained and unlikely negatively impacted by a system being unhealthy. Let's allow operating system updates even on unhealthy systems to help users getting back to a healthy state.

There are some unhealthy reasons (like duplicate OS installation) where we really don't want the users to update their OS, as it might break.

Let's remove docker_version from the unsupported reasons which make the system unhealthy.
