Bumps sigstore/cosign-installer from 3.10.0 to 4.0.0.

Release notes

Sourced from sigstore/cosign-installer's releases.

v4.0.0

What's Changed?

Note: You must upgrade to cosign-installer v4 if you want to install Cosign v3+. You may still install Cosign v2.x with cosign-installer v4.

In version v3+, using cosign sign-blob requires adding the --bundle flag which may require you to update your signing command.

  • Add support for Cosign v3 releases (#201)

v3.10.1

What's Changed?

Note: cosign-installer v3.x cannot be used to install Cosign v3.x. You must upgrade to cosign-installer v4 in order to use Cosign v3.

Note: This is planned to be the final release of Cosign v2, though we will cut new releases for any critical security or bug fixes. We recommend transitioning to Cosign v3.

  • Bump default Cosign to v2.6.1 (#203)

I'll see if I can massage the workflows a bit to be compatible with current cosign ...

Remove all uses of --rekor-url and --fulcio-url: looks like these should
just work based on TUF now.

it's not completely obvious to me that we're using the on-cluster versions of these services in this PR (looks like we might be reverting to PGI, which would not be what we'd want)?

there is a

TUF_MIRROR=$(kubectl -n tuf-system get ksvc tuf -ojsonpath='{.status.url}')
cosign initialize --mirror $TUF_MIRROR --root ./root.json

earlier in the workflow which I believe should handle this -- but I agree the order of these steps seems strange (and the cosign UX design is dangerous: using a non-default instance should always be obvious).

I may have to rethink this altogether because the on-cluster tuf repo is missing the signingconfig file
