Description
https://repo1.dso.mil/ironbank-tools/infra/ironbank-bootstrap/-/issues/2091
This MR supports https://repo1.dso.mil/ironbank-tools/infra/ironbank-bootstrap/-/issues/2091 by making a change to the validate_checksum function in the abstract_artifacts.py to get the get the raw skopeo output, save it to the cache and later compare that raw inspect to cache.
Risk
Unsure.
Rollback Plan
Can revert changes and go back to manually disabling cache on tag based manifests
