Consider adding version information to the Cluster status

[sbueringer]

User Story

As a user I would like to be able to access version information about my Cluster (topology) in the Cluster status.

Detailed Description

(this issue is based on the following conversation: #5292 (comment))

We currently only have version status information distributed over multiple resources:

• ControlPlane: .status.version (only applies to control plane providers using version, which is mandatory for ClusterClass)
• MachineDeployments: .spec.template.spec.version in combination with the replica status fields (?)
• MachinePool: .spec.template.spec.version in combination with the replica status fields (?)

If there is demand, it might be good to add summarized version information to the Cluster.status.

The control plane version (if it exists) could be e.g. used as the source of truth for any consumer, e.g a Node that does not want to break the kube version skew policy (kubelet vs apiserver) (quoted from #5292 (comment)).

Anything else you would like to add:

Are we envisioning a different status for managed and unmanaged Clusters?

Are we envisioning a different status for managed and unmanaged Clusters?

Good question. I'm not sure, but if I'm not mistaken the version part of it can be the same for both as the other resources are "connected" the same way to the Cluster resource independent of managed/unmanaged.
