feat: add default surname

[forderation]

add default surname for XML scheme before deposit.
a current existing plugin was an error when the family name is empty like this:

The content of element 'person_name' is not complete. One of '{"http://www.crossref.org/schema/4.3.6":surname}' is expected.

So the idea is use last section given name to provide surname when the family name is empty

Hi @forderation! The issue this is addressing is filed in Github with some discussion of a best approach here:

pkp/pkp-lib#7528

Have you seen that issue and its discussion?

yes the issue are same, but for alt-name i didn't see as well make the problem. AFAIK i already implemented in our modified ojs 3.2.1 and so far there is no problem with validation

Hi @forderation, thanks for putting this together! I've taken a look and left a few comments.

The discussion in pkp/pkp-lib#7528 recommends putting the OJS given name in the Crossref surname field if there is no family name provided in OJS. The pubmed plugin has a good example of how this has already been implemented in OJS:

https://github.com/pkp/ojs/blob/c8bba4d113a40ae3b9d997d90271b342aa8f9d29/plugins/importexport/pubmed/filter/ArticlePubMedXmlFilter.inc.php#L220-L235

Given the discussion mentioned in the issue and the pubmed example, I would recommend using a similar approach here as well. That way the same problems are solved in the same way across the code base. Thanks!
