[IMP] website_blog: perf - related author name avoid query res.partner

We use `author_id` (res.partner record) to instanciate our frontend widget
address so it can be changed through left panel in a searchable list.
This require a read on res.partner to get his name, even for visitors.

Using a related will have the same result for visitors while it won't need to
query res.partner table.
