feat: add job.workflow_* context properties

Add workflow_ref, workflow_sha, workflow_repository, and
workflow_file_path to the job context for reusable workflow jobs.
These fields provide direct access to the workflow file information
without needing to parse github.workflow_ref.

- Add 4 new fields to getJobContext() in job.ts
- Add descriptions in descriptions.json
- Update autocomplete test expectations
- Add validation and unit tests
