Maybe support for a build after tests

For rules repos, they tend to include some examples. Building (and testing) on the examples is useful to make sure they always work, but it would be nice to do that `build` & `test` after the "main" `build`/`test` on the repo as that main pair is going to include specific tests for all the rules/features of the repo. So if something breaks in the examples, it will be less obvious exactly what went wrong compared to see the test results.

Right now, the examples end up mixed in, so if an example fails, you likely don't get as easy of output to pinpoint the issue on as seeing the tests fail would.
