Fix CI workflow (#103)

The description field is not part of the [workflow
scheme](https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-syntax#jobs)
and causes the entire workflow file to be ignored.

The `needs` dependencies tried to account for all instances of a matrix
job, but should have taken only the generic matrix job name. It will
automatically depend on all instances of the matrix job.
