What changed?
Configure Cosign keyless signing of all release artifacts to the (Goreleaser) release workflow. I am not sure this will work, but there is a fair chance it will. Goreleaser docs: https://goreleaser.com/customization/sign/. I searched the Internet for references, and it seems like Chainguard has done something around this. I just copied https://github.com/chainguard-dev/apko/blob/64e3ae0d1cf09e2e83dd384cd5a4f9c06d48e0a4/.goreleaser.yaml#L34-L39, which should end up like this (Assets; example): https://github.com/chainguard-dev/apko/releases/tag/v0.22.6.
Why was this change made?
