CHW-4610 CacheArtifactsNotFound

no cached artifacts found for the supplied repository, package, and version

Default message: no cached artifacts found for the supplied repository, package, and version
HTTP status: 404 (client)

Problem. Cache purge could not find any artifacts matching the supplied repository, package, and version. Cause. The artifacts were never cached, were already purged, or the coordinate is mistyped. Fix. Verify the coordinate via the package listing endpoint; if it truly is missing, the purge is a no-op and no further action is required. HTTP 404.
