Consider to change the return value when Eloquent model is updated

[Vitaliy-1]

Describe the bug
Originally, when eloquent model is updated, the method returns the number of updated rows from the primary table. E.g.,

Announcement::where('type_id', '=', '1')->update([
  'title' => 'Announcement Title'
  'type_id' => '2'
])

After refactoring, Models that are utilising settings table, will return the number of updated rows from the primary table and settings table.

1. Explore if this has any drawbacks.
2. Consider alternative option, return associative array with the number of updated rows from primary and settings table (pkp/pkp-lib#10328 Refactor Announcements #10382 (comment))
