[Feature]: Improve GitHub Workflow to use Composition

[seriouslysean]

Feature Summary

Remove run-npm-script and replace with composition

Detailed Description

See https://github.blog/changelog/2021-08-25-github-actions-reduce-duplication-with-action-composition/ for more information

Additionally look in to caching more of the pipeline since all our steps (linting, tests, e2e) all use the same node version, node_modules and files.

@seriouslysean would you say this has been accomplished with our current gh actions setup?

[seriouslysean]

I don't think so, there's probably better caching we can do with named builds, I'd leave this open imo if there's someone pretty passionate about docker.
