fix(ci): ensure Node.js version >=22 in workflows

[learnwithdevopsengineer3682]

Summary

This PR ensures that the CI workflow uses a Node.js version compatible with the project requirement (>=22), as defined in CONTRIBUTING.md.

Currently, the workflow does not explicitly set a Node.js version, which may result in CI running with a lower default version. This can lead to installer failures and inconsistent runtime behavior.

Poem

🐰 A workflow so fine, with Node setup in place,
npm caches racing across GitHub's space,
Version twenty-two hops, dependencies bound,
Two jobs now faster, with nary a sound! ✨

In @.github/workflows/nightly-e2e.yaml:
- Around line 42-46: Update the "Setup Node.js" steps in the cloud-e2e and
cloud-experimental-e2e jobs to use actions/setup-node@v6 (replace `@v4`) and add
the same cache configuration block used in other workflows (the cache:
node-modules/npm or the established cache inputs) so the step names "Setup
Node.js" match the other workflows; locate the two steps by the job names
cloud-e2e and cloud-experimental-e2e and the existing "Setup Node.js" action and
apply the version and cache changes there.
