GitHub Event Context missing: github.event.repository.name

Describe issue

GitHub repository name is available via GITHUB_REPOSITORY env var, however I was using the event context (github.event.repository.name) as that already handles split by / for you. I've noticed that this is missing, which was leading to an empty string evaluation in my workflow.

If I have time, and manage to walk my way around the codebase, I'll send a PR adding this to the runner context. Creating the issue to keep track of htis.
