Add a build step that uploads surefire test reports

Motivation:
When a build fails, the number one priority is figuring out why.
Having surefire test reports readily available on the Github Actions page will make this easier.

Modification:
Add a build step that uploads surefire test reports and attaches them as a check to the PR.

Result:
Easier to diagnose test failures on PRs.
