chore(api): replace non-canonical annotation with the correct one

[eofff]

Description

Renamed the internal annotation API group prefix in annotations.go from virt.deckhouse.io to internal.virtualization.deckhouse.io.
Also updated 3p-containerized-data-importer in build/components/versions.yml to chore/rename-deckhouse-anno-prefix to keep dependency behavior aligned with the prefix change.

Why do we need it, and what problem does it solve?

The previous annotation prefix looked like a public-facing API domain. This change makes the namespace explicitly internal and aligns the CDI dependency branch to avoid annotation-prefix mismatches across components.

What is the expected result?

Annotations produced by the controller now use the internal.virtualization.deckhouse.io/* prefix.
Builds consume the CDI branch that includes the same annotation-prefix rename.
