Jonathan Desrosiers 0c25dca719 Build/Test Tools: Use caching built into actions/setup-node.
This updates the `actions/setup-node` action to version 2.2.2 and takes advantage of the cache feature now built in. This removes the need for an additional step using `actions/cache` to cache NPM dependencies.

The cache key used will be `${{ runner.os }}-npm-${{ hashFiles('') }}`, which matches the recommendation in the `actions/cache` documentation and the key currently in use in the WordPress workflows.

Props gziolo.
Fixes #53584.
