Improve actions notifier for workflow_run (#37088) (#37099)

Backport #37088

Changes:

- Make `GetActionWorkflow` only convert the target workflow
- In `getActionWorkflowEntry`, use `branchName` instead of resolving the
default branch name from `commit.GetBranchName()`
- Add `ref` to `workflow_run` notify input to avoid the empty `ref`
