Add change to a spark test to see if it triggers workflow CI

[kbendick]

Now that I've reenabled actions for this repo, this should run the workflows file, do labeling, and run spark tests.

Open issues:

• Can't use paths-ignore in a workflow that was triggered by workflow_call:
  - https://stackoverflow.com/questions/66751567/return-passing-status-on-github-workflow-when-using-paths-ignore
  - Can use a step called paths-filter instead: https://github.com/dorny/paths-filter
• Example of using triggered workflow: https://dev.to/n3wt0n/avoid-duplication-github-actions-reusable-workflows-3ae8
• Main docs: https://docs.github.com/en/actions/learn-github-actions/reusing-workflows
