Update actions to silence Node.js 12 warnings and deprecations

[NotMyFault]

This PR intends to address the Node.js 12 deprecation warnings by updating various actions, and mitigates the set-ouput warning by switching the syntax.

I think you can also probably add a dependabot.yml configuration to check for github actions new version, something like

# Docs: https://docs.github.com/en/code-security/supply-chain-security/configuration-options-for-dependency-updates
version: 2
updates:
  - package-ecosystem: 'github-actions'
    directory: '/'
    schedule:
      interval: 'daily'
    labels:
      - 'github-actions'
