Always run extra test

Under the new workflow files, this test is included whenever we run our other
tests. Importantly, the post-test phase of the relevant workflows depend on this test
running successfully. We can't skip the test (for example [during
releases](https://github.com/pulumi/pulumi-aws/actions/runs/6032096288), since that blocks
the post-test actions).
