When the scorecard GitHub action is used for evaluation, the default GitHub Actions token lacks the necessary permissions to perform the branch protection check, resulting in the following generic access issue error:
"Reasoning: internal error: error during brancheshandler.setup: internal error: githubv4.query: resource not accessible by integration"

Often times maintainers fail to understand the error message and end up ignoring the check all together.
