This endpoint allows you to fetch all versions of a given processor, including the current draft version.

Versions are typically returned in descending order of creation (newest first), but this should be confirmed in the actual implementation. The draft version is the latest unpublished version of the processor, which can be published to create a new version. It might not have any changes from the last published version.
