Summary

make policy-webhook was compiling a wrong directory. I also added the compilation of the policy-webhook binary to the cosigned target.

CGO_ENABLED=0 go build -trimpath -ldflags "-buildid= -X sigs.k8s.io/release-utils/version.gitVersion=v1.7.1-4-g9008111-dirty -X sigs.k8s.io/release-utils/version.gitCommit=9008111af46dda51d5336b1570d8bf5fe896a524 -X sigs.k8s.io/release-utils/version.gitTreeState="dirty" -X sigs.k8s.io/release-utils/version.buildDate=2022-04-05T18:38:00Z" -o policy-webhook ./cmd/cosign/policy-webhook
stat /Users/hectorj2f/sigstore/cosign/cmd/cosign/policy-webhook: directory not found
