[later phase] [PP-1] Prune unused `Component` config entity versions

Overview

Blocked on 📌 Update `ComponentAudit::getConfigEntityDependenciesUsingComponent()` to support component versions Active .

We have component versions since 📌 Version component prop definitions for SDC and Code components Active . Subsequent issues/MRs refined it. As of 📌 Revisit storage of dependencies in separate table now we have separate deltas per component Active , Component::getDependencies() reflects the dependencies of all versions, the version-specific ones can be accessed using ::getVersionSpecificDependencies().

What's missing: pruning of old, unused versions. i.e. those with zero uses according to ComponentAudit::getConfigEntityDependenciesUsingComponent().

Proposed resolution
