build(deps): bump the actions group across 1 directory with 3 updates

[dependabot]

Bumps the actions group with 3 updates in the / directory: step-security/harden-runner, actions/download-artifact and sigstore/cosign-installer.

Updates step-security/harden-runner from 2.15.1 to 2.16.0

Release notes

Sourced from step-security/harden-runner's releases.

v2.16.0

What's Changed

• Updated action.yml to use node24
• Security fix: Fixed a medium severity vulnerability where the egress block policy could be bypassed via DNS over HTTPS (DoH) by proxying DNS queries through a permitted resolver, allowing data exfiltration even with a restrictive allowed-endpoints list. This issue only affects the Community Tier; the Enterprise Tier is not affected. See GHSA-46g3-37rh-v698 for details.
• Security fix: Fixed a medium severity vulnerability where the egress block policy could be bypassed via DNS queries over TCP to external resolvers, allowing outbound network communication that evades configured network restrictions. This issue only affects the Community Tier; the Enterprise Tier is not affected. See GHSA-g699-3x6g-wm3g for details.
