ci: bump actions to Node 24 majors

GitHub is deprecating the Node 20 runtime and force-running Node-20 actions
on Node 24. Bump every affected action to the major that natively targets
Node 24 to clear the deprecation warnings on both workflows:

- actions/checkout          v4 -> v5
- actions/setup-go          v5 -> v6
- crazy-max/ghaction-import-gpg  v6 -> v7
- goreleaser/goreleaser-action   v6 -> v7
- golangci/golangci-lint-action  v7 -> v9
- hashicorp/setup-terraform      v3 -> v4

No behavior change: golangci-lint-action v8+ only requires golangci-lint
>= v2.1.0 (we pin v2.12.2), and setup-terraform v4 keeps terraform_wrapper.
release.yml stays in sync with test.yml's pinned versions.
