Exporting results needs a parameter to specify the version

When exporting results via the API, there is no information in the results to indicate which version the results are based upon. This leads to a situation that if the survey has been edited (and even not published) on the platform, the exported results would not reflect the actual survey that was presented to the respondent. This is obviously an issue for data integrity,
The export results API method (and even the on platform one) needs to either export the survey structure based on the most recently published survey (why would anyone want to export results based on an unpublished survey?) or at the very least include a paramter in the query to specify the version id to base the export on.
