[MC-276506] Written book title/author fails to use JSON formatting

When you give yourself a written book through commands u are unable to use JSON formatting for the title nor the author

Reproduce:
Commands:

   /give @s written_book[written_book_content={title:{raw:'{"text":"Should be Title"}'},author:'{"text":"Should be Author"}'}]

   /give @s written_book[written_book_content={title:'{"text":"Should be Title"}',author:'{"text":"Should be Author"}'}]

JSON formatting should work with any string set for displays/item names...
