🔧 Restore Node after SDK release notes (#289)

## Why

The static-site SDK release failed before tests/publish because the
Codex changelog action switches the active job runtime back to Node 20.
Our SDK release workflows install pnpm 11, which requires Node 22+, so
the next pnpm command crashed before the package could test or publish.

The warning points at `actions/setup-node@49933...` because that
setup-node call lives inside `openai/codex-action`, not in these
workflows. This PR fixes the breakage by setting the release job runtime
back to our supported Node version immediately after Codex runs.

## What changed

- Adds a post-Codex `actions/setup-node@v6` step in the Storybook,
Static Site, Vitest, and Ember SDK release workflows.
- Resets those jobs to Node 22.13.1 before `pnpm install`, tests, build,
pack, and publish.
- Keeps the release workflows single-job and avoids extra changelog
plumbing.
- Leaves Ruby and Swift unchanged because they do not run pnpm/npm after
Codex in their release flows.

## Verification

- `git diff --check HEAD^ HEAD`
- Parsed all six SDK release workflow YAML files with Ruby.
