Current Limitation

Currently we are using v1 for setting up Node.js along with manual dependency caching step.

Feature / Enhancement Description

We could upgrade the action to v2 and use built-in dependency caching: https://github.com/actions/setup-node#caching-packages-dependencies

This would allow us to slightly simplify workflows.
