List Question Versions - Plugixa Exam

GET /plugixa-exam/v1/questions/{id}/versions

List every saved version of a question, newest first, each with a full snapshot of the question at that version.

Not reachable with an API token: since 1.4.1 a token request to this route answers 403 plugixa_exam_token_route. Call it as a signed-in WordPress user (from a script, with an Application Password) who holds the questions:view permission.

Note. The question is not checked to exist: an unknown id answers 200 with an empty list, not 404. The list is not paged. For a lighter list without the snapshots, see Get Question History PRO.
