Use namespace for stage images

[ehelms]

Why are you introducing these changes? (Problem description, related links)

This will simplify the process for stage vs. production by keeping the image name consistent and only changing the namespace. This will also allow using registry overrides to switch between stage and production. See https://github.com/containers/image/blob/main/docs/containers-registries.conf.5.md#remapping-and-mirroring-registries

@Odilhao I think this will be beneficial, but this needs some coordination with actually publishing

[Odilhao]

Here's the PR that we can use for it, we would need to merge https://gitlab.com/fedora/infrastructure/konflux/tenants-config/-/merge_requests/192 and later update all component-oci repos to build using the new path with stage/component/. Another important topic is to provision the new quay namespaces.

Thanks @Odilhao. I've opened theforeman/foreman-oci-images#43 to link back to this documentation. Once merged I can open similar PRs to the other repositories.

theforeman/candlepin-oci-images#31 and theforeman/pulp-oci-images#29 for the trifecta. Also opened theforeman/pulp-oci-images#28 because I like consistency.

Should we mention that this structure makes it easy to use Podman's registry mirror functionality to switch from release to staging?
