Sign container images
Is your feature request related to a problem? Please describe. Images pushed to GHCR are not signed.
Describe the solution you'd like Images pushed to GHCR should be signed to verify integrity and establish chain of trust.
Additional context GitHub recommends https://github.com/sigstore/cosign-installer per https://github.blog/2021-12-06-safeguard-container-signing-capability-actions/ so this does not seem like it would be very complicated to enable. Open to alternatives from anyone with experience signing images in GHA.
sigstore (cosign?) can also be used to sign the OCI helm chart https://helm.sh/docs/topics/registries/#using-sigstore-to-sign-oci-based-charts
I made a PR to address this one. Please help assign and review if possible. Thanks!
