A book should specify if it's an anthology and display "(number) authors" on book cards

Is your feature request related to a problem? Please describe.

I am filling the info for an anthology (https://www.goodreads.com/book/show/56752890-out-of-the-ruins). There are 19 authors. I don't need the 19 authors to be listed on book cards. The 19 authors only need to be listed on the book page.

Describe the solution you'd like

• When editing a book, I can check "This is an anthology" in the Authors section.
• If a book has multiple authors and is an anthology, when displayed as a card, the full list of authors won't be shown. Instead the displayed list will be 19 authors.
• Depending on the context, the displayed list can have more info. For example, if displaying an Author Page for author Charles Writington-Penhandler, the list of authors should display Charles Writington-Penhandler and 18 others (displaying the name of one author and the number of other authors). Same with Search results displaying the name of the corresponding author(s) from an author list.
• If a book has multiple authors and is an anthology, the book page should list all authors.

This is a good idea! This is happening when authors are displayed in the timeline already, which probably isn't directly useful, but at least is a similar pattern :)
