fix(release): add Node.js 22 setup for type stripping support (#114)

## Summary

The release scripts use `node --experimental-strip-types` which requires
Node.js 22.6+. The default Node.js on GitHub Actions runners is older,
causing the pre-release command to fail with:

```
node: bad option: --experimental-strip-types
```

## Changes

- Add `actions/setup-node@v4` with `node-version: 22` to ensure type
stripping works
