update "time" fields (creationTime and publicationTime) into files

[ChengShi-1]

What inspired the request?
This issue is inspired when I found that once the file uploaded, it was always saved as midnight 12:00 AM UTC, regardless of the hour, and 12:00 AM UTC was as 7:00 PM EST on the previous day (my local time zone). This discrepancy caused the file date in the front-end page, followed users' local timezone, to appear a day earlier than the intended date. For example, I uploaded the file Nov. 14 would be saved Nov.14 12:00 AM UTC, but shown Nov. 13 locally due to a conversion from UTC to EST. Thus, in order to prevent the time zone conflict, a timestamp with actual time could help.

Overview of the Feature Request
In filePayload.ts, update the creationDate and pulicationDate from
{"creationDate": string, "publicationDate": string}
to
{"creationDate": string, "creationTime": date, "publicationDate": string, "publicationTime": date}
like
{"creationDate": "2024-11-14", "creationTime":"2024-11-15T21:40:25Z", "publicationDate": "2024-11-14", "publicationTime": "2024-11-15T21:40:25Z"}

Also, fileTransformer, fileModel and all related files need to be changed.

After discussion, we don't need the timestamp for creationTime and publicationTime. Thus, I transferred the one from dataverse repo to js-dataverse repo. --> #223

This one should be closed due to duplication.
