Show failing checks only (or sort checks by failing / running / queued / cancelled) #3791

When having hundreds of tests, it is difficult to switch to the failing ones.

Example:

Proposal:

Sort the list of check outputs by "priority": failing, running, queued, cancelled. Therein by name.

Alternatively, a filter showing the failing tests only would be helpful, too.

The URL should be each pull request (e.g., https://github.com/latextemplates/generator-latex-template/pull/25)
