Navigation links: add the link target settings to the block inspector

[afercia]

Description

While editiing navigation links and submenus I noticed the 'link target' setting is only available in the link editing UI popover, while it is absent in the block inspector.

As a user, this is confusing to me. I would expect the block inspector settings panel to let me access all settings ot a block.

For consistency, I'd suggest to add it to the 'Advanced' section of the block inspector.

Can we just duplicate the entire "Advanced" section verbatim into the inspector?
