oai.content_dm.arck validation results

fixes requested

• is_shown_by: currently mapped as an array(?); please map as a string -- see example in 27587 report
• type / format: Rikolti is dropping one of the "format" values (3D Image), which is derived from dc:type
  We are expecting 3 values to in "format"
  The vernacular metadata includes 1 format: <dc:format>.obj</dc:format> & 2 types: <dc:type>3D Image</dc:type> <dc:type>Image</dc:type>
  Legacy is mapping all three of these to format: obj; 3D Image; Image & one of these to type: image
  Rikolti is mapping only two of these to "format": ["obj", "image"] (dropping 3D Image). (Rikolti continues to also map "type": ["image"])
  Please investigate why Rikolti is dropping "3D Image" from its list of formats; see example in 27587 report

resolved issues

• alternative title: map <dc:alternative> (add to the base oai mapper)
  (Note that our previous requests indicated to add <dcterms:alternative>. We'd like you to add both of these to the base mapper.)

Alternative title should be addressed when any of the OAI mappers PRs are merged.

Thanks! #27591 is a good collection to test. Thank you!

Lucas checked the base oai mapper work addresses the alternative title issue.
