Suggestion: Send series information to DataCite as RelatedItem of type "IsPublishedIn” instead of description of type "SeriesInformation"

Overview of the Suggestion

We've received a request to change the way information in the "Series" metadata field (citation block) is sent to DataCite.

Currently, it is sent as a description of type "SeriesInformation":

<description descriptionType="SeriesInformation">My Series</description> 

(https://github.com/IQSS/dataverse/blob/develop/src/main/java/edu/harvard/iq/dataverse/pidproviders/doi/XmlMetadataTemplate.java#L1365-L1383)

The DataCite schema PDF states that

SeriesInformation
Definition: Information about a repeating series, such as volume, issue, number.
Usage Notes: The information previously encoded as a description with this type should now be explicitly provided in tagged fields using the new 20. RelatedItem property with relationType “IsPublishedIn” selected.

(since version 4.4 update)

What existing behavior do you want changed?

We'd like to suggest changing the XML sent to DataCite to use the new format (RelatedItem property with relationType “IsPublishedIn”) when sending the "Series" metadata.

Are you thinking about creating a pull request for this issue?
Help is always welcome, is this idea something you or your organization plan to implement?

Yes, we would open a PR for this

Start in src/main/java/edu/harvard/iq/dataverse/pidproviders/doi/XmlMetadataTemplate.java at lines 1365-1383, then compare the current Series mapping with the DataCite 4.5 schema guidance for RelatedItem and relationType “IsPublishedIn”. Done means the Series metadata is emitted using the requested RelatedItem format rather than a SeriesInformation description.
