Use production date in citation for harvested dataset

[tcoupin]

What this PR does / why we need it:

Date in citation div is the "citation date" which is most of th time the publication date (the first release date) (https://guides.dataverse.org/en/latest/api/native-api.html?highlight=citationdate#set-citation-date-field-type-for-a-dataset).

But for a harvested dataset, the distribution date is used instead and this date is not always present. With oai_dc format the date tag if used as production date (when harvesting (see code) AND serving (see code)).

This PR try to use production date for harvested dataset in addition to distribution date

Which issue(s) this PR closes:

• Closes Year in citations of harvested datasets is always current year #8103

@tcoupin from a very quick look I think we'll need some documentation. A small change to the guides would be great and lasting (more lasting than a release note). In addition, a release note fragment would be nice so we can highlight the change. Please see https://guides.dataverse.org/en/5.10.1/developers/making-releases.html#write-release-notes

Hi @pdurbin
Release note added.
But I don't found any section in the guide about citation building to update. The PR affects only the citation generation.

[pdurbin]

@tcoupin thanks, you're probably right about the guides.

I hope you don't mind but I'm using your PR to trigger a build on our Jenkins server. 😄
