[Schema Inaccuracy] 'head_repository' on workflow run might also be null

[paescuj]

Schema Inaccuracy

Apparently, the head_repository property can also be null in the Get a workflow run response. I assume this happens when the repository has been removed in the meantime.

Expected

The head_repository property should also list null as a possible variant.

Reproduction Steps

# Run with empty 'head_repository'
curl --silent https://api.github.com/repos/fkirc/skip-duplicate-actions/actions/runs/2379220866 | jq '.head_repository'

# "Normal" run
curl --silent https://api.github.com/repos/fkirc/skip-duplicate-actions/actions/runs/2419547490 | jq '.head_repository'
