kbs: Remove oci.kbs version and references

Our KBS logic currently checks out the git.kbs version of code, but then edits the deployment config to override the image based on the oci.kbs version. This means that there is an assumption that the oci image of the KBS is compatible with the kustomization, which might not not always be the case and in the "always safe" case where the image is built from that exact version of code (e.g. releases), just means that we have to specify it in two places, so there isn't much advantage to this approach. This PR removes the oci.kbs image and versioning to avoid this potential incompatibility and simplify trustee version updates. Because there is a chance that the trustee team might not keep their kustomizational image up-to-date, the recommendation is that we should ensure that the image version matches the branch we are using, so perform a kustomize set image at the time we clone the repo.
