Provide an API endpoint for retreiving a list of contributors (translators or reviewers) for a project version within a time frame.
Returning a list of user identifiers should suffice here. Details about the contributions could come from a separate API call to the existing endpoint which retrieves the statistics for a project.
An initial idea for this endpoint is something like:
This would bring it in line with the other APIs we have been adding (protocol and url wise). We need to check that this url does not conflict with others that we have at the moment.
