Add workflow_run api + webhook (#33964)

Implements 
- https://docs.github.com/en/rest/actions/workflow-jobs?apiVersion=2022-11-28#list-jobs-for-a-workflow-run--code-samples
- 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
- [x] Verify Keda Compatibility
- [x] Edit Webhook API bug is resolved
 
Closes https://github.com/go-gitea/gitea/issues/23670
Closes https://github.com/go-gitea/gitea/issues/23796
Closes https://github.com/go-gitea/gitea/issues/24898
Replaces https://github.com/go-gitea/gitea/pull/28047 and is much more
complete
