fix: add missing labels to issue form templates

GitHub silently hides issue forms that contain a field without an
`attributes.label`. The `version` field in bug-report.yml and the
`affected-command` field in feature-request.yml were missing labels,
so the entire forms were dropped from the new-issue chooser.

Add the required labels (and a helpful description) so all three
templates render in the UI.
