workflow_call: event payload should be same as caller

[rva-kvanheck]

Gitea Version

1.27.1

What happened?

Before v1.27, the event payload for workflow payload events was the same as the caller.
The following conditional in a workflow triggered by workflow_call worked as expected before v1.27:
if: ${{ github.event_name == 'push' }}

Expected event payload documentation:
