ci: pin golangci-lint v2 in the release workflow

- The release Validate job used golangci-lint-action@v6, which
  installed a golangci-lint built with Go 1.24 — it refuses to
  run against the module's Go 1.26 target, failing the gate.
- Match ci.yml: action@v9 + version v2.12.2 (v2 is built with
  current Go and matches the v2 .golangci.yml schema).
