feat(ci): test rolling over release to release (#2195)

Description
Adds CI coverage for rolling Deckhouse Virtualization from one release to another in a persistent nested e2e cluster.

The PR introduces a dedicated release e2e workflow and reusable pipeline that:

bootstraps a nested cluster for release testing;
configures required storage backends and SDN/ClusterNetwork resources;
installs Virtualization from the current release and runs pre-upgrade release scenarios;
patches the Virtualization ModulePullOverride to the new release;
runs post-upgrade release scenarios against the same test resources;
keeps encrypted cluster artifacts available for debugging.
It also adds release-specific e2e scenarios and helper resources for validating VM lifecycle, guest access, networking, storage attachment, and upgrade continuity.
