ci: github actions workflow improvements

[voxpelli]

Overview

The major benefit is that the workflows are lot DRY:er now – main definition is only 40 lines of code since all the repetitive boilerplate is ripped out into a reusable part:

mocha/.github/workflows/mocha.yml

Lines 16 to 56 in 19ae145

	jobs:
	lint:
	uses: ./.github/workflows/npm-script.yml
	with:
	npm-script: lint
	smoke:
	uses: ./.github/workflows/npm-script.yml
	with:
	os: 'ubuntu-latest,windows-2019'
	node-versions: '14,16,18,20,22'
	npm-script: test:smoke
	test-node:
	# TODO: Restore "mocha-github-actions-reporter" style reporting without relying on third party module
	uses: ./.github/workflows/npm-script.yml
	needs: smoke
	with:
	os: 'ubuntu-latest,windows-2019'
	node-versions: '14,16,18,20,22'
	npm-script: test:node
	coverage: true
	test-browser-local:
	needs: smoke
	uses: ./.github/workflows/npm-script.yml
	with:
	browsers: ChromeHeadless
	npm-script: test:browser
	test-browser-saucelabs:
	# Don't run forked 'pull_request' without saucelabs token
	if: github.event_name == 'push' || !github.event.pull_request.head.repo.fork
	needs:
	- smoke
	- test-browser-local
	uses: ./.github/workflows/npm-script.yml
	secrets: inherit
	with:
	browsers: 'firefox@latest,chrome@latest,MicrosoftEdge@latest,safari@latest'
	npm-script: test:browser

This also ensures that the caching, installation etc will behave consistently in all the places and makes it easy to evolve it in a consistent manor.

🚀 This is fantastic, thanks for the cleanup!

Nothing blocking from me. Just a couple of questions.
