Overview of the Feature Request
In JSF File page, for each file, we could download citation in different format

Similar to what in dataset page (refer to native api Get Citation In Other Formats

Dataverse can also generate dataset citations in “EndNote”, “RIS”, “BibTeX”, and “CSLJson” formats. Unlike the call above, which wraps the result in JSON, this API call sends the raw format with the appropriate content-type (EndNote is XML, RIS and BibTeX are plain text, and CSLJson is JSON). (“Internal” is also a valid value, returning the same content as the above call as HTML). This API call adds a format parameter in the API call which can be any of the values listed above.
