Include job name in gh pr checks #4916

Describe the feature or problem you’d like to solve

We have a number of services we test in every PR. There is one workflow per service, with a test job within that workflow.

In the PR view you can see [Workflow name] / [job name] which lets you disambiguate checks.

However in the CLI output, you can only see the job name, so it's not easy to tell which job actually failed:

Proposed solution

Include the Workflow name in the output (perhaps only if there is more than one workflow running?)

This will let cli users do more from the CLI without having to open the GitHub website.

Additional context

Perhaps something more like this?
