Bump github.com/sigstore/cosign/v2 from 2.3.0 to 2.4.0

[dependabot]

Bumps github.com/sigstore/cosign/v2 from 2.3.0 to 2.4.0.

Release notes

Sourced from github.com/sigstore/cosign/v2's releases.

v2.4.0 begins the modernization of the Cosign client, which includes:

• Support for the newer Sigstore specification-compliant bundle format
• Support for providing trust roots (e.g. Fulcio certificates, Rekor keys) through a trust root file, instead of many different flags
• Conformance test suite integration to verify signing and verification behavior

In future updates, we'll include:

• General support for the trust root file, instead of only when using the bundle format during verification
• Simplification of trust root flags and deprecation of the Cosign-specific bundle format
• Bundle support with container signing

We have also moved nightly Cosign container builds to GHCR instead of GCR.

Features

• Add new bundle support to verify-blob and verify-blob-attestation (#3796)
• Adding protobuf bundle support to sign-blob and attest-blob (#3752)
• Bump sigstore/sigstore to support email_verified as string or boolean (#3819)
• Conformance testing for cosign (#3806)
• move incremental builds per commit to GHCR instead of GCR (#3808)
• Add support for recording creation timestamp for cosign attest (#3797)
• Include SCT verification failure details in error message (#3799)

Hi @dependabot[bot]. Thanks for your PR.

I'm waiting for a tektoncd member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
