workflows/eval: use consistent naming with the other 3 PR workflows

The overall idea is to use names short enough to fit into the status
checks list without shortening. This change mostly happened in the
commits before, here we just follow the same pattern for the remaining
workflows.

(cherry picked from commit c08b86e962)
