Summary

This makes the auto format workflow obtain the head SHA from the PR that triggered the workflow run directly.

This improves security because even if an attacker managed to upload a malicious artifact by manipulating their PR, they could no longer abuse that to push to arbitrary PRs because the SHA sum wouldn't match.
