Note: The Checks API only looks for pushes in the repository where the check suite or check run were created. Pushes to a branch in a forked repository are not detected and return an empty pull_requests array.

Creates a new check run for a specific commit in a repository. Your GitHub App must have the checks:write permission to create check runs.

In a check suite, GitHub limits the number of check runs with the same name to 1000. Once these check runs exceed 1000, GitHub will start to automatically delete older check runs.
