• https://docs.github.com/en/rest/actions/workflow-jobs?apiVersion=2022-11-28#get-a-job-for-a-workflow-run--code-samples
• https://docs.github.com/en/rest/actions/workflow-runs?apiVersion=2022-11-28#list-workflow-runs-for-a-repository
• https://docs.github.com/en/rest/actions/workflow-runs?apiVersion=2022-11-28#get-a-workflow-run
• /actions/runs for global + user + org (Gitea only)
• /actions/jobs for global + user + org + repository (Gitea only)
• workflow_run webhook + action trigger
  • limitations
    • workflow id is assigned to a string, this may result into problems in strongly typed clients

Fixes

• workflow_job webhook url to no longer contain the runs/<run> part to align with api
• workflow instance does now use it's name inside the file instead of filename if set

Refactoring

• Moved a lot of logic from workflows/workflow_job into a shared module used by both webhook and api

TODO

• Verify Keda Compatibility
• Edit Webhook API bug is resolved

Closes #23670
Closes #23796
Closes #24898
Replaces #28047 and is much more complete

Ready for review?

[ChristopherHX]

My time to respond or make changes is limited in the next seven days, due to exams.

Other than that, yes I think this is ready for review.

[wxiaoguang]

No hurry, overall looks good. Thank you very much.

(Maybe will take a look again later)

[wxiaoguang]

Did another round review. I think it looks good to me.

Is there anything else to change? If no, let's merge ~~ 🙏

Nothing that I am aware of, I agree with merging this now. Then I can polish the keda scaler side of things soon and move that one out of a draft.
