Automated Tests

Important

This PR is a draft while I experiment with testing strategies. This should not be considered ready for review.

Adds a way to validate workflows in an isolated organization.

Tests:

• reusable-github-matrix-tg.yml
  • Test to validate we can generate a matrix (happy path)
  • Test to confirm a workflow failure when the platform/ folder does not exist
• reusable-pr-label-by-branch.yml (using our default release-drafter config)
  • The first PR receives a major label
  • PR branches prefixed with bug, fix, and patch receive a patch label
  • PR branches prefixed with feature receive a minor label
  • PR branches prefixed with any of the above and a ! character receive a major label
  • PR branches with any other prefix are not labeled.
