Description

This is a follow-up for open-component-model/ocm#1699.

In open-component-model/ocm#1699 we ignored the package github.com/sigstore/sigstore because it introduced a breaking change (see release notes ) that breaks github.com/sigstore/cosign/[email protected]:

# github.com/sigstore/cosign/v2/pkg/cosign
Error: /home/runner/go/pkg/mod/github.com/sigstore/cosign/[email protected]/pkg/cosign/keys.go:143:24: undefined: cryptoutils.ValidatePubKey
Error: /home/runner/go/pkg/mod/github.com/sigstore/cosign/[email protected]/pkg/cosign/keys.go:152:24: undefined: cryptoutils.ValidatePubKey
Error: /home/runner/go/pkg/mod/github.com/sigstore/cosign/[email protected]/pkg/cosign/keys.go:163:25: undefined: cryptoutils.ValidatePubKey

A fix is already prepared, see open-component-model/ocm#1699 (comment)
