fix potential GitHub Actions smells

[ceddy4395]

Summary

Describe what the PR does and how to test. Photos and videos are recommended.

Hey! 🙂 I want to contribute the following changes to your workflow:

• Avoid executing scheduled workflows on forks
• Avoid uploading artifacts on forks
• Stop running workflows when there is a newer commit in branch
• Stop running workflows when there is a newer commit in PR

(These changes are part of a research Study at TU Delft looking at GitHub Action Smells. Find out more)

Review / Merge checklist

• [ ] PR title and summary are descriptive. Remember, the title automatically goes into the changelog. Use (no-changelog) otherwise. (conventions)
• [ ] Docs updated or follow-up ticket created.
• [ ] Tests included.

  A bug is not considered fixed, unless a test is added to prevent it from happening again. A feature is not complete without tests.
