[bug] workflow_run.completed returning empty pull request array

workflow_run.completed returning empty pull request array

currently, when a workflow_run.completed is triggered by a pull request from a forked repository, the workflow_run.completed returns an empty pull request array payload. the payload does not contain necessary pull request information, resulting in an empty pull request array when the pull request comes from a forked repository.

our maintainers is actively investigating this issue and we're currently working on a solution in pull request #45 to address this problem.
