build: rename workflow_dispatch input labels for the GH UI

The GitHub Actions UI uses the input 'description' as the field label
on workflow_dispatch. The previous wording read awkwardly (e.g. 'If
true, evaluate without committing or notifying Slack' as a checkbox
label). These shorter, label-style descriptions render cleanly.
