Cannot checkout branch from private fork

[ddlan]

Describe a bug

When raising a PR to a repo from a private fork, the github action fails when trying to check out the PR branch because it does not have access to the private remote.

Expected behavior

The github action should be able to check out the PR HEAD commit by hash and run test coverage.
