Github-workflow: Report both failures and errors

Port of changes from https://github.com/containers/podman/pull/12997 and
https://github.com/containers/podman/pull/13005 to the workflow in this
repository.

***Note***: Impractical to automatically verify these changes until
they're merged into `main`.  Though the similar changes made in the
podman repo. have been manually confirmed to function as intended.
