OJS should support publications authored by organizations and anonymous authors

[AhemNason]

This issue describes two problems -- a bug and a feature request.

~~1. The feature request is that OJS should support publications without a specific author. This leads to bad metadata and downstream services, like Crossref, support author-less objects.~~ ~~2. The section option "omit authors from table of contents" is not respected and the default theme shows authors anyway. This should be addressed in line with how we handle author-less publications.~~

(Authorless comments are filed/resolved in https://github.com/pkp/pkp-lib/issues/8403.)

Original comment:

In journal section metadata/options, there's a qualifier to omit the author's name from a journal section. This is, by and large, a workaround for journals publishing articles that don't have an "author". Stuff like errata or abstracts collections or any other number of things. These are usually uploaded by managing editors or other journal staff who are also authors of legitimate materials.

All themes, including default, display these author names on the table of contents even if the radial to not display them is selected.

You can find the relevant setting in Journal>Sections>Edit>Omit Author from Journal section...

I'd add that this should also omit the author from citations, the article landing page, and any other associated metadata. This whole feature is a workaround due to not being able to zero out an author field, but the downstream impact of that stored metadata is also potentially problematic.

Author email addresses should no longer be required. (https://github.com/pkp/pkp-lib/issues/3561)
