test(deps): update actions/setup-node to v7

[MikeMcC399]

Situation

Workflows and examples currently use the GitHub Actions actions/setup-node version v6.

GitHub has released actions/setup-node@v7 with updated caching.

Change

Update all usage of actions/setup-node in examples and documentation

BEFORE	AFTER
actions/setup-node@v6	actions/setup-node@v7

Comment

This is a manual update because Renovate only updates workflow, not the corresponding documentation, which would leave the runnable examples out of sync with the documentation.

---

Note

Low Risk
Dependency-only bump in CI and docs; no application or Cypress action logic changes, though v7’s caching behavior could affect workflow cache hits until caches warm again.

Overview
Bumps actions/setup-node from v6 to v7 everywhere Node is installed in CI and in copy-paste examples.

Workflows under .github/workflows/ (main, check-dist, and the example-* jobs for npm, pnpm, Yarn Classic/Modern, and Node version matrices) now reference actions/setup-node@v7. Existing with: settings (Node version, cache, cache-dependency-path) are unchanged.

README.md workflow snippets are updated the same way so documentation stays aligned with the runnable workflows (pnpm, Yarn Modern, package-manager caching, Node versions, tags).
