Subject: [PATCH] ci(deps): bump cosign-installer to v4.1.2, pin cosign CLI to
 v2.5.2

Supersedes Dependabot #59. Bumping sigstore/cosign-installer from v3 to
v4.1.2 changes its default cosign CLI to v3.0.6, which removed the
sign-blob --output-signature / --output-certificate flags the release
signing step uses (v3 replaced them with --bundle). Pinning cosign-release
to v2.5.2 keeps the detached .sig/.pem signing working while taking the
updated installer action.
