feat: make `talosconfig` and `talosconfigtemplate` immutable

[Unix4ever]

This change is made to conform CAPI practices for resource updates: instead of modifying the templates/configs, it is necessary to create a new one.

If the resource is always recreated, rolling update strategy will be able to pick up the change and redeploy machines.

does this mean the retrieved talosconfig becomes invalid on updates?

TalosConfig resource is what controls generation of Talos machine configuration, generated client talosconfig is stored as a per-cluster secret
