Subject: [PATCH 1/2] Modernize GitHub Actions workflow and migrate cosign to
 v2.

Bumps all action SHA pins to current major versions and updates cosign from v1.4.0 to v2.4.1, which is required because cosign-installer v1's download URLs stopped serving binaries after Sigstore deprecated their GCS bucket releases in July 2023.
