ci: Update GitHub Actions to next stable version

[matthewfeickert]

Description

• Update GitHub Action workflows:
  • Use actions/checkout v3 for all workflows.
  • Use github/codeql-action/init v2.
  • Use github/codeql-action/analyze v2.
  • Use hadolint/hadolint-action v2.1.0.

Don't touch the tag.yml workflow though as that's going to be deprecated soon, and it is best not to touch something important and difficult to test like that.
