Deprecate the stackstate-k8s-agent in favor of the SUSE Observability agent

[craffit]

StackState was rebranded to SUSE observability and the agent chart to SUSE Observability Agent

The SUSE Observability Agent chart is distributed as part of the rancher prime chart repository, so this chart is now deprecated.

Hi @craffit and @recena, this isn't the right way to deprecate a chart. The right way is to use the partner-charts-ci deprecate command. This sets Deprecated: true in upstream.yaml, but also adds deprecated: true to the Chart.yaml of each chart version for that chart. This second part is important because it makes the chart show up as deprecated in the rancher UI.

@craffit is there any chance you could submit another PR for this that uses partner-charts-ci deprecate?

I will update the documentation for the Deprecated field (and the Hidden field, where this also applies) so that this doesn't happen in the future.

You are right. My mistake. @adamkpickering Can you revert this PR and prepare a new one?

[adamkpickering]

Certainly. @craffit please disregard my previous request. I'll have another PR up shortly
