🐛 Update webapp for public #solr_document

[kirkkwang]

Story

This commit will update the hyrax-webapp submodule where we move the #solr_document method from private to public. The method being private was causing a crash in the Universal Viewer. As per Hyrax, the method should have been public in the first place.
