It seems the workflow_run trigger only calls the workflow as it is on
the default branch (ie `main`). This would make it difficult to make
changes to this workflow and set of tests.

This will run the cli ui (bats) tests in a separate workflow from the
build workflow. This takes advantage of the newer workflow_run event to
trigger the tests after the build has completed, so that the artifacts
from the build step can still be used.
